        "content": "Here\u2019s a rundown of how DigitalOcean handles email-related services, both what they offer and what they *don\u2019t* provide, as of March 2026.\n\n---\n\n## What DigitalOcean *Doesn\u2019t* Offer\n\n- **Native Email Hosting**: DigitalOcean does *not* provide a built-in service for hosting email accounts (like *@yourdomain.com*) for sending and receiving emails. If you need a mailbox (e.g. email hosting), you'll need to use a third-party provider. ([digitalocean.com](https://www.digitalocean.com/community/questions/does-my-digitalocean-account-come-with-an-email-server-setup?utm_source=openai))\n\n- **Open SMTP Ports by Default**: Outbound SMTP ports 25 (unencrypted), 465 (SMTPS), and 587 (submission) are blocked by default on their Droplets (virtual private servers). This is done to reduce spam, abuse, and reputation issues. ([docs.digitalocean.com](https://docs.digitalocean.com/support/why-is-smtp-blocked/?utm_source=openai))\n\n---\n\n## What DigitalOcean *Does* Offer for Email\n\nWhile they don\u2019t provide email hosting out-of-the-box, DigitalOcean does offer a few related email solutions and support for integrating third-party providers:\n\n1. **Marketplace \u201cSelf-Hosted Email Server\u201d App**\n   - DigitalOcean offers a 1-Click Marketplace application that sets up an email server (using open-source tools like Postfix and Dovecot). This allows you to deploy your own mail server on a Droplet and manage sending/receiving email. ([docs.digitalocean.com](https://docs.digitalocean.com/products/marketplace/catalog/self-hosted-email-server/?utm_source=openai))\n\n2. **Service for an SMTP Port Unblocking Request**\n   - Although ports 25, 465, and 587 are blocked for new accounts by default, in some cases DigitalOcean will review and remove those restrictions (after confirming legitimate use, proper domain setup, etc.). ([community.wappler.io](https://community.wappler.io/t/smtp-issues-on-digital-ocean/63278?utm_source=openai))\n\n3. **Recommendations to Use Third-Party Email-as-a-Service (EaaS) Providers**\n   - Because setting up your own mail server is complex (spam filters, reputation, deliverability), DigitalOcean encourages using external providers like SendGrid, Mailgun, or other transactional/marketing email services. ([docs.digitalocean.com](https://docs.digitalocean.com/support/why-is-smtp-blocked/?utm_source=openai))\n\n---\n\n## Considerations & Best Practices\n\n- If you want to **receive emails**, you'll need to configure DNS records like MX, SPF, DKIM with your email host. DigitalOcean\u2019s role here is setting up DNS\u2014but not providing mailboxes. ([digitalocean.com](https://www.digitalocean.com/community/questions/does-my-digitalocean-account-come-with-an-email-server-setup?utm_source=openai))\n\n- For **sending emails**, you have two main paths:\n  1. Use a third-party SMTP or send-by-API service. These avoid the blocked ports issue (either by using ports like 2525 that are allowed, or by using HTTP APIs). ([reddit.com](https://www.reddit.com/r/digital_ocean/comments/1ksj9fs?utm_source=openai))  \n  2. Try to self-host via the Marketplace app\u2014but still need to handle blocking and email deliverability issues. Also likely need to request port unblocking. ([docs.digitalocean.com](https://docs.digitalocean.com/products/marketplace/catalog/self-hosted-email-server/?utm_source=openai))\n\n- **Deliverability & Reputation**: Operating your own mail server means managing IP reputation, maintaining reverse DNS, and ensuring spam prevention measures. Mistakes here can send your emails to spam, or your IP could get blacklisted. This is one reason DigitalOcean blocks standard SMTP ports by default. ([docs.digitalocean.com](https://docs.digitalocean.com/support/why-is-smtp-blocked/?utm_source=openai))\n\n---\n\nIf you tell me what you\u2019re trying to do\u2014send transactional emails, receive emails on your domain, route newsletters, etc.\u2014I can help you pick the right setup or provider that works well with DigitalOcean."

    },
    {
        "role": "assistant",
        "content": "Yes \u2014 you *can* use `isync`/`mbsync` together with NeoMutt. The two work really well together: `mbsync` handles syncing your mail via IMAP to a local store; NeoMutt reads that store in whatever format you choose. What matters is picking a mailbox format that plays nicely in terms of speed, concurrency, reliability with multiple tools, and how NeoMutt treats new mail detection.\n\nHere\u2019s a breakdown of what formats are supported, what\u2019s good or bad about each, and which is likely best for your setup.\n\n---\n\n## Supported Mailbox Formats in NeoMutt\n\nNeoMutt supports four local mailbox (storage) formats. When you create new local folders/mailboxes, the type used is decided by the `$mbox_type` config variable (or with `-m` on the command line) ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai)).\n\nThe formats are:\n\n- **mbox** \u2014 All messages in a single file; classic UNIX mailbox format.  \n- **MMDF** \u2014 Similar to mbox but uses special delimiters (control-A\u2019s) between messages.  \n- **MH** \u2014 Each message is a separate file in a directory; includes support for sequences, roughly like Maildir but simpler.  \n- **Maildir** \u2014 Messages are files in `new/`, `cur/`, `tmp/` directories; uses no locking; robust with concurrency; reasonably efficient for syncing. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))\n\n---\n\n## Pros & Cons of Each Format with `mbsync` + NeoMutt\n\nHere\u2019s how each stacks up when using `mbsync` + NeoMutt on a typical setup (local disk, possibly SSD):\n\n| Format | Strengths with mbsync + NeoMutt | Weaknesses / Things to Watch |\n|--------|----------------------------------|-------------------------------|\n| **Maildir** | Great: No file-locking needed. Very safe if NeoMutt and mbsync run simultaneously (e.g. while aliasing or checking mail). New-mail detection is reliable because presence of files in `new/` is clearly visible. Works well with multiple tools using message filenames for metadata. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai)) | Many small files\u2014directory scans can be slower, especially if you have lots of email messages/folders. Can be space-inefficient depending on compression or filesystems. May need header caching if many files/folders. |\n| **MH** | Also message-per-file, but simpler structure. Good concurrency, avoids some of the locking problems of mbox. | Less common; fewer tools support it. Slightly more complex to set up compared to Maildir. |\n| **mbox** | Very simple; easy for backups. One file per folder. If folder count stays small, performance is decent. | Locking issues if accessed by multiple processes (mbsync + NeoMutt + maybe something else). Corruption risk. New-mail detection less reliable; entire file must be checked for changes. Writes to large files can be slower and costly. |\n| **MMDF** | Similar trade-offs as mbox but rarer; used only in more specialized cases. | Even less widely supported; same drawbacks as mbox; pretty much avoid unless you have a specific need. |\n\n---\n\n## What\u2019s Common / Recommended\n\nBased on what people frequently do, what\u2019s in documentation, and what works well in practice:\n\n- **Maildir** is the go-to choice for most users syncing with `mbsync` and reading with NeoMutt. It gives good reliability, handles concurrency well, and works nicely with other tools (searchers, indexers, etc.).  \n- If you expect large numbers of messages, many subfolders, and want the smoothest experience, Maildir + header caching in NeoMutt makes sense.  \n- If you prefer simpler structure and want something more like classic UNIX mail setup, mbox *can* work\u2014just be mindful of what happens when you have multiple processes reading/writing.\n\n---\n\n## Sample Config Snippet (mbsync + Maildir + NeoMutt)\n\nHere\u2019s what a basic setup might look like for mbsync + NeoMutt using Maildir:\n\n```ini\n# .mbsyncrc\nIMAPAccount remote\nHost imap.fastmail.com\nUser you@yourdomain.com\nSSLType IMAPS\n\nMaildirStore local\nPath ~/Mail/yourdomain/\nInbox ~/Mail/yourdomain/INBOX\nSubFolders Verbatim\n\nChannel fastmail\nMaster :remote:\nSlave :local:\nPatterns *\nCreate Both\nSync All\nExpunge Both\n```\n\nAnd NeoMutt\u2019s config excerpt:\n\n```muttrc\nset mbox_type=Maildir\nset folder=\"~/Mail/yourdomain\"\nset spoolfile=\"+INBOX\"\nmailboxes = +INBOX +Sent +Archive +Trash\n# optionally set maildir specific options\nset maildir_check_cur=yes\n```\n\n---\n\n## Final Recommendation\n\nFor your use case (using `mbsync` + NeoMutt):\n\n**Go with Maildir** unless you have a good reason otherwise.\n\nHere\u2019s why:\n\n- It\u2019s robust for concurrency: NeoMutt and mbsync won\u2019t trample each other.\n- New-mail detection is clean and accurate.\n- Lots of existing users/configs use this combo; you\u2019ll find help more easily.\n- Good balance between performance and reliability. If things slow with millions of emails, you can use caching tools or split into subfolders.\n\nIf you tell me your expected scale (number of emails per folder, frequency of access, etc.), I can help you tune things (e.g. header cache, folder layout, etc.)."

These examples show both the on-disk layout and file/message naming conventions.\n\n---\n\n## Maildir Structure\n\nIn Maildir, every *mailbox folder* is a directory; inside each mailbox folder there are always three special subfolders: `tmp`, `new`, and `cur`. Messages are individual files.\n\nHere\u2019s a sample layout using Maildir++ (hierarchical folder names prefixed with a dot) or FS layout (plain directory hierarchy). Let\u2019s assume base folder is `~/Maildir`.\n\n**Example:**\n\n```\n~/Maildir/\n\u251c\u2500\u2500 cur/\n\u251c\u2500\u2500 new/\n\u251c\u2500\u2500 tmp/\n\u251c\u2500\u2500 .Sent/\n\u2502   \u251c\u2500\u2500 cur/\n\u2502   \u251c\u2500\u2500 new/\n\u2502   \u2514\u2500\u2500 tmp/\n\u251c\u2500\u2500 .Archive/\n\u2502   \u251c\u2500\u2500 cur/\n\u2502   \u251c\u2500\u2500 new/\n\u2502   \u2514\u2500\u2500 tmp/\n\u251c\u2500\u2500 .Trash/\n\u2502   \u251c\u2500\u2500 cur/\n\u2502   \u251c\u2500\u2500 new/\n\u2502   \u2514\u2500\u2500 tmp/\n\u2514\u2500\u2500 .Drafts/\n    \u251c\u2500\u2500 cur/\n    \u251c\u2500\u2500 new/\n    \u2514\u2500\u2500 tmp/\n```\n\nWhere:\n\n- `~/Maildir/` is your INBOX (top\u2010level mailbox).\n- `.Sent/`, `.Trash/`, `.Archive/`, `.Drafts/` are subfolders under Maildir. The leading dot indicates hidden folders in Maildir++ layout. In FS layout, you might use `Maildir/Sent/`, `Maildir/Trash/`, etc., without the dot prefix. ([doc.dovecot.org](https://doc.dovecot.org/2.4.0/core/config/mailbox/formats/maildir.html?utm_source=openai))\n\n---\n\n## MH Structure\n\nMH (or `nmh`) uses one message per file *and* one directory per mailbox folder, but it doesn\u2019t enforce the `tmp/new/cur` layout. Instead, each folder is merely a directory containing numbered message files and possibly some control or sequence metadata.\n\nHere\u2019s how a similar setup might look:\n\n```\n~/MailMH/\n\u251c\u2500\u2500 INBOX/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u251c\u2500\u2500 2\n\u2502   \u251c\u2500\u2500 3\n\u2502   \u2514\u2500\u2500 \u2026   (each number is a separate message file)\n\u251c\u2500\u2500 Sent/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u251c\u2500\u2500 2\n\u2502   \u2514\u2500\u2500 \u2026\n\u251c\u2500\u2500 Archive/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u251c\u2500\u2500 2\n\u2502   \u2514\u2500\u2500 \u2026\n\u251c\u2500\u2500 Trash/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u2514\u2500\u2500 \u2026\n\u2514\u2500\u2500 Drafts/\n    \u251c\u2500\u2500 1\n    \u2514\u2500\u2500 \u2026\n    \u2514\u2500\u2500 .mh_sequences\n```\n\nWhere:\n\n- The top-level directory `MailMH` contains mailbox folders (`INBOX`, `Sent`, `Archive`, `Trash`, `Drafts`).\n- Within each, files `1`, `2`, `3`, \u2026 are individual messages.\n- There's likely an `.mh_sequences` file in the base folder or in specific folders that tracks message \u201csequences\u201d (a kind of internal numbering/filtering/tagging). ([en.wikipedia.org](https://en.wikipedia.org/wiki/MH_Message_Handling_System?utm_source=openai))\n\n---\n\n## Comparison at a Glance\n\n| Feature | Maildir | MH |\n|---|---------|----|\n| Folder naming | directories with subfolders `tmp`, `new`, `cur` per mailbox | directories containing message files |\n| Message storage | one file per message, safe for concurrent writes | one file per message too |\n| Handling new/unread messages | `new/` holds new; when read moved (or flagged) to `cur` | every message file present; unread/read status handled via filenames or message metadata (often external) |\n| Folder hierarchy | can use dot\u2010prefix (Maildir++) or filesystem hierarchy | simple directories; nested by filesystem folder tree |\n\n---\n\nIf you like, I can also generate a sample of what the internal file names look like (e.g. for messages in `cur/new` in Maildir) or show how sequence files in MH work. Do you want that?"

You can use this with NeoMutt (or Mutt) to read locally.\n\n```ini\n# ~/.mbsyncrc\n\nIMAPAccount gmail\nHost imap.gmail.com\nUser your.email@gmail.com\n# It's better to use OAuth2 or an App Password if you have 2FA enabled\nPassCmd \"gpg --quiet --for-your-eyes-only --no-tty -d ~/.auth/gmail\u2010app\u2010password.gpg\"\nSSLType IMAPS\n# If needed:\n#SslVersions TLSv1.2\n\nIMAPStore gmail-remote\nAccount gmail\n\nMaildirStore gmail-local\nPath ~/Maildir/gmail/\nInbox ~/Maildir/gmail/INBOX\n\n# Gmail uses label \"[Gmail]/Sent Mail\", \"[Gmail]/Trash\", \"[Gmail]/All Mail\"\n# Also labels can be in language variant, adjust if your Gmail is localized\n\nChannel gmail-inbox\nFar :gmail-remote:\nNear :gmail-local:\nPatterns \"INBOX\"\nCreate Both\nSyncState *\nExpunge Both\n\nChannel gmail-sent\nFar :gmail-remote:\"[Gmail]/Sent Mail\"\nNear :gmail-local:Sent\nCreate Both\nSyncState *\nExpunge Both\n\nChannel gmail-trash\nFar :gmail-remote:\"[Gmail]/Trash\"\nNear :gmail-local:Trash\nCreate Both\nSyncState *\nExpunge Both\n\nChannel gmail-archive\n# If you want to sync Gmail's \u201cAll Mail\u201d or a custom archive label\nFar :gmail-remote:\"[Gmail]/All Mail\"\nNear :gmail-local:Archive\nCreate Both\nSyncState *\nExpunge Both\n```\n\n### Notes & tweaks\n\n- `PassCmd` or `Password` can be used; if you have two-factor auth, using an *App Password* or OAuth is necessary.  \n- `Create Both` ensures that if local or remote folder doesn\u2019t exist, it'll be created.  \n- `Expunge Both` removes deleted messages.  \n- `SyncState *` ensures that state tracking works for *all* channels.  \n- Adjust the Gmail folder names carefully: `[Gmail]/Sent Mail`, `[Gmail]/Trash`, etc., exactly as Gmail shows them in your locale.  \n- Local folder names like `Sent`, `Trash`, `Archive` get created under `~/Maildir/gmail/`.  \n\n---\n\nIf you *do* want a pure MH\u2010local format version of the `.mbsyncrc` (i.e. syncing into MH folders), I can also give you that. Do you prefer MH local or Maildir local?"

Here\u2019s what I found, and what your options are.\n\n---\n\n## What I found: MH + Syncing Tools\n\n- **Fetchmail** can fetch email from Gmail via IMAP (or POP), and you can deliver fetched messages into an MH folder using **procmail** with `mda`. In other words, fetchmail pulls the mail, procmail routes it to MH. ([fetchmail.info](https://www.fetchmail.info/fetchmail-FAQ.html?utm_source=openai))  \n- The mh/nmh documentation shows workflows using fetchmail/inc + `mh/inc` (or equivalent commands) to bring fetched messages into the MH \u201cinbox.\u201d ([thierr26.github.io](https://thierr26.github.io/email_with_nmh_and_other_cli_programs.html?utm_source=openai))  \n- But crucially, no tool like **mbsync/isync** or **offlineimap** supports **MH** storage for the *local* side. Their local stores are Maildir. ([en.wikipedia.org](https://en.wikipedia.org/wiki/OfflineIMAP?utm_source=openai))\n\n---\n\n## Conclusion\n\nSo: yes, you *can* sync Gmail with MH format\u2014but **not** using mbsync/isync, since they **can\u2019t write to MH**. You need a different pipeline, typically involving:\n\n1. **Fetchmail** or `getmail` (or IMAP client/daemon that supports fetching)\n2. Delivery agent (`procmail` or an equivalent MDA) that puts mail into MH folders (using the `.mh` subdirectory notion).\n3. Use MH utilities (nmh/mmh) to read/manage the MH directory.\n\n---\n\n## How to Set Up Gmail \u2192 MH Workflow\n\nHere\u2019s a sample configuration you *could* use (combining fetchmail + procmail + MH). This is how people do it, since there's no plug-and-play mbsync way.\n\n### 1. `.fetchmailrc`\n\n```text\n# ~/.fetchmailrc\n\nset daemon 300     # poll every 300 seconds (5 min)\npoll imap.gmail.com with proto IMAP\n    user \"your.email@gmail.com\" there with password \"YOUR_APPPASSWORD\"\n    ssl\n    # fetch all, keep on server (optional)\n    fetchall\n    keep\n    mda \"/usr/bin/procmail -f %F\"\n```\n\n- Use an App Password if you have two-factor auth on Gmail.\n- `keep` ensures Gmail messages aren't deleted. Remove if you want delete\u2010after\u2010fetch.\n\n### 2. `.procmailrc`\n\n```text\n# ~/.procmailrc\n\nDEFAULT=$HOME/Mail/ # base MH directory\nMAILDIR=$HOME/Mail\n\n# this delivers to MH inbox folder (i.e. ~/Mail/INBOX/)\n# deliver to MH folder: use \u201c/. \u201d to indicate MH\n# see procmail doc: ending mailbox name in \u201c/.\u201d means MH\n:0\n* ^TO_Your\\.address@gmail\\.com\nINBOX/.\n\n# any spam / other rules\n:0\n* ^X-Spam:.*Yes\nMail/.Spam/.\n```\n\n- Note: using `INBOX/.` means deliver into MH folder `INBOX` under `~/Mail/` directory. The trailing `/.` is key. ([unix.stackexchange.com](https://unix.stackexchange.com/questions/336420/how-do-you-use-procmail-mda-to-deliver-files-to-be-read-by-mh?utm_source=openai))\n- For other Gmail labels/folders, fetch with IMAP and add more rules in procmail, or replicate label structure with MH subdirectories.\n\n### 3. MH Folder Structure Example\n\nAfter setup, your local mail directory may look like:\n\n```\n~/Mail/\n\u251c\u2500\u2500 INBOX/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u251c\u2500\u2500 2\n\u2502   \u2514\u2500\u2500 \u2026 (individual message files)\n\u251c\u2500\u2500 Sent/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u2514\u2500\u2500 \u2026\n\u251c\u2500\u2500 Trash/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u2514\u2500\u2500 \u2026\n\u251c\u2500\u2500 Archive/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u2514\u2500\u2500 \u2026\n\u251c\u2500\u2500 Spam/\n\u2502   \u251c\u2500\u2500 1\n\u2502   \u2514\u2500\u2500 \u2026\n\u2514\u2500\u2500 .mh_sequences   # MH\u2019s sequence file\n```\n\n---\n\nIf you like, I can write a full working example\u2014including rules for syncing Gmail\u2019s Sent, Trash, Archive labels\u2014to MH using fetchmail + procmail + MH. Do you want me to build that out for you?"

However, Gmail is *ending POP3 & Gmailify* for new uses in 2026 ([wired.com](https://www.wired.com/story/gmail-killing-pop-and-gmailify-access-what-it-means-for-you?utm_source=openai)). IMAP remains. |\n| **Fastmail** | IMAP enabled; supports \u201cfetching\u201d external accounts; can use app-specific passwords | Works smoothly with fetchmail or getmail + external MDA delivery into MH. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000278022?utm_source=openai)) |\n| **Most standard email providers** (Outlook.com, Yahoo Mail, etc.) | IMAP or POP3 support (though varying toggle defaults, authentication modes) | Any provider with reliable IMAP/POP lets tools like fetchmail, getmail fetch mail into MH using external MDA. |\n\n---\n\n## Sync / Fetch Methods That Pair Well with MH/nmh\n\nThese tools let you retrieve messages and deliver into MH-style storage, either directly or via external delivery agents.\n\n| Tool | Description | How you hook into MH |\n|---|---|---|\n| **getmail / getmail6** | Fetches mail via IMAP or POP3; supports external MDAs | With `destination = MDA_external` you can specify `rcvstore` (nmh\u2019s message insertion tool) so new messages go into MH folders. ([getmail6.org](https://getmail6.org/faq.html?utm_source=openai)) |\n| **fetchmail** | Classic fetcher; retrieves mail and passes to local delivery agents | Use fetchmail \u2192 procmail \u2192 MH folders (using `rcvstore`) to integrate into MH. Works with almost any server supporting IMAP or POP3. ([fetchmail.info](https://www.fetchmail.info/fetchmail-FAQ.html?utm_source=openai)) |\n| **Procmail / other MDAs** | Filter and deliver messages locally | Can put mails into `~/Mail/<folder>/` using MH delivery syntax (e.g. using `rcvstore +folder`) to populate your MH/Mail root. |\n\n---\n\n## Things to Watch Out For\n\n- **POP3 support ending / deprecated**: Gmail is shutting down POP3 / \u201cFetch mail from other accounts\u201d functionality in 2026 ([wired.com](https://www.wired.com/story/gmail-killing-pop-and-gmailify-access-what-it-means-for-you?utm_source=openai)). If you rely on POP for getting mail from external accounts, you may lose that option.  \n- **Authentication**: Many providers are requiring stronger auth (OAuth2, app passwords). Older tools like fetchmail may not support OAuth2 well. If your provider requires OAuth3 or \u201cno plain auth,\u201d that could be a blocker.  \n- **Folder/Label mapping**: Gmail uses labels rather than strict folders; mapping them cleanly into MH folder directories typically requires ignoring or remapping some labels.  \n- **Rate limits / access policies**: Providers may restrict IMAP connections, or enforce quotas or limits. Tools must do polling responsibly.  \n\n---\n\n## Summary\n\nIf you want to use mh / nmh and keep things robust:\n\n- Use a provider that supports IMAP (Fastmail is a good example; Gmail still does, but with changing rules).  \n- Use **getmail** (preferred) or **fetchmail** + procmail + `rcvstore` to deliver into MH folders.  \n- Avoid relying on POP3 long\u2010term (especially with Gmail).  \n- Make sure you set up authentication in a way the provider accepts (e.g. app passwords, maybe OAuth2).  \n\nIf you like, I can list a few specific providers that *currently allow* MH workflows by real users, so you can pick one."

Here\u2019s a detailed breakdown of what works well, and things to watch out for.\n\n---\n\n## Why Fastmail Is a Good Fit\n\n1. **Full IMAP Support**  \n   Fastmail provides full IMAP access (on their Standard / Professional / paid Individual plans) with SSL/TLS, allowing clients to download from any folder, sync status (read/unread, flags etc), and maintain folder structure. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000279921-IMAP-POP-and-SMTP?utm_source=openai))\n\n2. **POP3 Available (if needed)**  \n   For simpler setups or just inbox backup, Fastmail also supports POP3. But POP3 isn't ideal if you want to sync folder structure or status. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000279921-IMAP-POP-and-SMTP?utm_source=openai))\n\n3. **App Passwords / Strong Authentication**  \n   To access via IMAP from third-party tools (like fetchmail/getmail), Fastmail requires app-specific passwords (especially when two-step verification is enabled). ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000279921-IMAP-POP-and-SMTP?utm_source=openai))\n\n---\n\n## Why Fetchmail Works Well\n\n- **Protocol flexibility**: Fetchmail supports both IMAP and POP for fetching. With IMAP, you can fetch from specific folders, retain status where possible, etc. ([fetchmail.info](https://www.fetchmail.info/fetchmail-FAQ.html?utm_source=openai))  \n- **Delivery agents (MDA)**: You can set up fetchmail so that once messages are retrieved, an external MDA like **procmail** or **rcvstore** (nmh\u2019s message inserter) delivers them into specific MH folders. That gives you full control over how mail ends up in your `.mh` directories. ([fetchmail.info](https://www.fetchmail.info/fetchmail-FAQ.html?utm_source=openai))\n\n---\n\n## Things to Confirm / Check Before You Start\n\n- **Fastmail Plan Requirements**:  \n  The \u201cBasic\u201d plan does *not* allow IMAP/SMTP carddav-/caldav-based external client access. You\u2019ll need a plan that supports external clients. ([reddit.com](https://www.reddit.com/r/fastmail/comments/1hjaxl1?utm_source=openai))\n\n- **Folder-structure mapping**:  \n  Make sure the folder/label naming on the Fastmail side works well with MH folders. For example, \u201cSent\u201d, \u201cInbox\u201d, \u201cArchive\u201d\u2014if the names differ, you'll want your MDA or fetch rules to map them cleanly. Because MH folders are literally directories, the names matter.\n\n- **Authentication**:  \n  Set up an app-password for Fetchmail (or whichever fetcher you use) so you don\u2019t have issues with blocking or forced web/OAuth flows. Fastmail explicitly requires that for external client access. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000279921-IMAP-POP-and-SMTP?utm_source=openai))\n\n- **Status / flags syncing**:  \n  While IMAP often preserves read/unread and flags, fetchmail may not always preserve everything\u2014especially if you use \u201ckeep\u201d or \u201cdrop\u201d modes. You\u2019ll want fetchmail configured to preserve UIDs, and deliver in a way that doesn\u2019t strip metadata.\n\n---\n\n## Basic Example Workflow\n\nHere\u2019s a sketch of how you might wire things up:\n\n1. Set up a Fastmail account (on a plan with IMAP/SMTP enabled).\n2. In `~/.fetchmailrc`, configure IMAP access:\n\n   ```\n   poll imap.fastmail.com with proto IMAP\n     user \"me@fastmail.com\"\n     password \"APP_PASSWORD\"\n     ssl\n     keep\n     mda \"/usr/bin/procmail -f %F\"\n   ```\n\n3. In your `~/.procmailrc`, use rules to deliver messages into MH folders:\n\n   ```\n   DEFAULT=$HOME/Mail/\n   MAILDIR=$HOME/Mail\n\n   :0\n   * ^To.*me@fastmail.com\n   INBOX/.\n\n   :0\n   * ^From.*someone@special.com\n   Important/.\n   ```\n\n   Or alternatively, use `rcvstore` (nmh) to deliver directly into MH format.\n\n4. Run fetchmail periodically (daemon mode or via cron) so new mail is fetched and delivered.\n\n5. Use MH/nmh utilities (`scan`, `show`, `pick`, etc) for reading/managing your mail locally.\n\n---\n\nIf you want, I can build a full sample setup with `getmail6 + rcvstore` (nmh-friendly) and Fastmail, with detailed configs you can drop in. Do you want that?"

Fetchmail itself **does not** support bi-directional sync. It only handles **retrieving** remote mail (POP3 / IMAP) and delivering it **locally**, via SMTP or using a local MDA (Mail Delivery Agent). ([fetchmail.info](https://www.fetchmail.info/fetchmail-FAQ.html?utm_source=openai))\n\nHere\u2019s what that means, and what workarounds people use.\n\n---\n\n## What Fetchmail *Can\u2019t* Do\n\n- Fetchmail does **not** send changes (flags, deletions, moves) that you make locally in an MH store back to the remote server. It doesn\u2019t mirror what you do in your local folders back to Gmail, Fastmail, etc. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Fetchmail?utm_source=openai))  \n- It does **not** support sending composed mail from the MH store back through the remote provider\u2019s SMTP server. Sending mail is completely separate: MH / nmh has its own outgoing tools (like `post`, `send`, etc.), which rely on a configured SMTP client or MTA. So outbound mail sync is not part of fetchmail\u2019s job.  \n- Fetchmail does **not** deliver directly into MH folders (directories) *by itself*. It fetches and then either:\n  - sends via SMTP to a local MTA that then delivers, or  \n  - invokes a local MDA (e.g. procmail, maildrop) to place messages into user mailboxes. ([fetchmail.info](https://www.fetchmail.info/fetchmail-man.html?utm_source=openai))\n\n---\n\n## What *Can* Be Done / Workarounds for Syncing Back\n\nTo get something more \u201ctwo-way,\u201d there are a few possible arrangements:\n\n1. **Use an IMAP client that works directly with MH folders**\n\n   There are clients or scripts that map IMAP state (read/unread, flagged, moved, deleted) into an MH folder tree. You\u2019d need something to push local folder changes *back* to IMAP. Tools like `imap-sync` or custom scripts might help. But this isn\u2019t fetchmail.\n\n2. **Manual / periodic repush**\n\n   You could, for example, periodically synchronize local \u201cSent\u201d folder contents up to the server via SMTP. Or use something like `imap-upload` to upload messages in an MH \u201cSent\u201d folder to the remote \u201cSent Items\u201d folder. But this won\u2019t automatically mirror reads, deletes, etc.\n\n3. **Use a full IMAP-based workflow**\n\n   If you choose to use an IMAP client as your primary view (e.g. Thunderbird, mutt, or other IMAP capable tools) you get two-way syncing naturally. Meanwhile, MH could be for archival, processing, or scripting. But that means not using MH as the only mail agent.\n\n4. **Alternative fetch tools that support outgoing + flag sync**\n\n   Some people prefer **getmail** (or **getmail6**) combined with **isync/mbsync** (for syncing IMAP folders bidirectionally). However, mbsync writes to **Maildir**, not MH; you'd still need a converter or custom layout. So while it gives you two-way synchronization, it's not native MH.\n\n---\n\n## Summary\n\n- If by \u201cthe other way\u201d you mean having local changes reflect upstream (on the server): fetchmail by itself can\u2019t do that.\n- Fetchmail is reliably \u201cremote \u279d local.\u201d Local \u279d remote (sent mail, flag changes, deletes, moves) is **not** supported by it out of the box.\n- To get a more full sync, you\u2019ll likely need IMAP-based tools or additional custom scripting.\n\nIf you want, I could walk through a possible setup that *does* allow some local \u2192 remote sync (for example syncing the \u201cSent\u201d folder, or read flags), using existing open-source tools. Do you want to explore that?"

        "content": "Yes \u2014 NeoMutt *can* do (quite a lot of) two-way syncing when you use it with IMAP. It supports uploading changes (flags, moves, deletions) back to the server, as well as sending outgoing mail via SMTP. But how \u201ccomplete\u201d the sync is depends on your configuration. Here\u2019s how it works and what to watch out for.\n\n---\n\n## What NeoMutt *Can* Do with IMAP\n\nNeoMutt has built-in support for IMAP (and secure IMAPS), allowing you to:\n\n- Open and browse remote IMAP folders/mailboxes. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n- Create, delete, rename remote folders (mailboxes) via commands like `<create-mailbox>`, `<delete-mailbox>`, `<rename-mailbox>` in the IMAP folder browser. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n- Mark messages read/unread, flagged/unflagged, etc., and have those flags synced back to the server. NeoMutt has code paths for sending updated flags to the IMAP server. ([code.neomutt.org](https://code.neomutt.org/imap_imap.html?utm_source=openai))  \n- Move or delete messages. Deletion is usually via marking for deletion then expunging, which NeoMutt supports. ([code.neomutt.org](https://code.neomutt.org/imap_imap.html?utm_source=openai))  \n- Send outgoing mail via SMTP using either built-in SMTP support or an external \u201csendmail\u201d equivalent. So your \u201cSent\u201d folder (remote or local) can be set up to receive outgoing messages. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n\n---\n\n## How to Trigger Syncs\n\nSome actions are synced back automatically; others may require you to explicitly invoke them:\n\n- There\u2019s a command (bound to `$` by default) called `<sync-mailbox>` that you use to write back local changes (flags, deletions) to the remote IMAP server. Closing a mailbox or switching to another one often triggers this implicitly. ([unix.stackexchange.com](https://unix.stackexchange.com/questions/566501/mutt-mail-read-unseen-flag-not-syncing-with-server?utm_source=openai))  \n- When you \u201cmove\u201d messages (via NeoMutt\u2019s UI) from one IMAP folder to another, that is also synced. ([code.neomutt.org](https://code.neomutt.org/imap_imap.html?utm_source=openai))  \n\n---\n\n## What Sync Doesn\u2019t Always Cover\n\nBut there are some limitations or gotchas to be aware of:\n\n- **Local-only folders**: Sometimes people mix reading from remote (IMAP) with local MH/Maildir/Mbox archives. Moves inside local stores won\u2019t affect the server. For two-way fancier archiving workflows, you\u2019ll need tools that manage syncing those local stores with the server.  \n- **Offline changes**: If you make changes while offline, NeoMutt needs to reconnect and sync. Sometimes conflicts or missing updates can happen (e.g. if another client also changes a message).  \n- **\u201cSent\u201d folder duplication / behavior**: Depending on server settings, you may end up with duplicate \u201cSent\u201d messages (stored by both NeoMutt and server auto-archiving). You\u2019ll want to configure `set record = \"+Sent\"` etc carefully. ([futurile.net](https://www.futurile.net/2025/05/18/neomutt-email-native-imap-tutorial?utm_source=openai))  \n- **Server limitations**: If your provider limits which flags can be changed, or how folder renames work, or doesn\u2019t support expunge properly, you may hit limits. Also, some servers use unusual folder hierarchy separators, or special folder names. NeoMutt has settings to help manage that. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n\n---\n\n## Example Configuration Snippet for Two-Way Sync\n\nHere\u2019s a minimal example showing the relevant settings in `~/.muttrc` (or `~/.neomuttrc`) to get both read/write sync and outgoing mail:\n\n```\n# IMAP server\nset folder     = \"imaps://user@imap.example.com:993\"\nset spoolfile  = \"+INBOX\"\nset imap_user  = \"user@example.com\"\nset imap_pass  = \"<APP_PASSWORD_OR_OAUTH_TOKEN>\"\n\n# Folders for common special purposes\nset record     = \"+Sent\"     # where Sent mail goes\nset postponed = \"+Drafts\"    # drafts\nset trash      = \"+Trash\"\n\n# Make sure those are known\nmailboxes $spoolfile +Sent +Drafts +Trash\n\n# Outgoing via SMTP\nset smtp_url = \"smtp://user@smtp.example.com:587\"\nset smtp_pass = \"<same or different as needed>\"\n\n# Sync mailbox command\n# ($ is bound to <sync-mailbox> by default)\n```\n\nWith this setup:\n\n- Reading, deleting, moving, flagging messages in those IMAP folders will reflect on the server as you go or after invoking `$`.  \n- Sent messages will go into your remote Sent folder.  \n- Drafts/trash go where you\u2019ve specified.  \n\n---\n\n## In Conclusion\n\nSo, in short:\n\n- Yes, NeoMutt *can* do most two-way syncing with an IMAP server: reading, moving, deleting, flagging messages, and sending new messages.  \n- It isn\u2019t perfect for offline workflows unless configured carefully and paired with tools (or careful habits).  \n- If your goal is a fully mirrored local archive, you might still want something like `mbsync` / `isync` for offline copies, with NeoMutt as your access UI.  \n\nIf you like, I can help you set up a NeoMutt config + folder layout for your provider (Fastmail, Gmail, etc.) that gives you good two-way sync."

([reddit.com](https://www.reddit.com/r/fastmail/comments/1hjaxl1?utm_source=openai)) | \u2022 Some features like folder name separators may require adjustment. <br> \u2022 Ensure the plan supports IMAP/SMTP\u2014Fastmail\u2019s Basic plan *does not*. ([reddit.com](https://www.reddit.com/r/fastmail/comments/1hjaxl1?utm_source=openai)) <br> \u2022 \u201cFetch\u201d (Fastmail's import/fetch-from-other-account tool) is not the same as full IMAP sync with another provider\u2014it\u2019s more of a one-way fetch. ([reddit.com](https://www.reddit.com/r/fastmail/comments/1cvmi9w?utm_source=openai)) |\n| **Gmail / Google Workspace** | Also strong, with caveats | \u2022 Supports IMAP and SMTP with proper configuration. Flags, reads, deletes, moves all sync. <br> \u2022 Supports OAuth2 auth (important for NeoMutt setup). <br> \u2022 Many users report it works well for typical workflows. | \u2022 Gmail offers \u201clabels\u201d rather than folders; NeoMutt has to map Gmail\u2019s IMAP behavior (e.g. \u201cAll Mail\u201d). <br> \u2022 Some quirks like performance for \u201cAll Mail\u201d folder when using certain settings. <br> \u2022 Google is phasing out POP/Gmailify for third-party accounts as of early 2026. ([techradar.com](https://www.techradar.com/pro/google-set-to-end-pop3-support-heres-what-we-know?utm_source=openai)) <br> \u2022 Requires app password or OAuth2 when 2FA is turned on. |\n| **ProtonMail (with Bridge)** | Good with constraints | \u2022 The Bridge lets you use ProtonMail via local IMAP/SMTP, making it compatible with NeoMutt. <br> \u2022 Encryption/decryption happens via the Bridge; mails on server are still protected. ([proton.me](https://proton.me/blog/gluon-imap-library?utm_source=openai)) | \u2022 Bridge is only available for **paid** accounts. ([proton.me](https://proton.me/support/imap-smtp-and-pop3-setup?utm_source=openai)) <br> \u2022 POP3 is not supported; only IMAP + SMTP via the Bridge. <br> \u2022 Since Bridge is local, it must be running to access mail via NeoMutt; not as seamless as direct IMAP. <br> \u2022 Some delay or performance overhead noted by users. |\n| **iCloud Mail** | Decent, with some quirks | \u2022 IMAP/SMTP access is supported, allowing basic two-way syncing. <br> \u2022 Folders like Sent, Trash, Drafts are available. <br> \u2022 Generally works with NeoMutt once configured. | \u2022 Some folder naming / hierarchy issues; sometimes special folders are named non-intuitively. <br> \u2022 Some mailboxes may appear \u201cnonexistent\u201d depending on path syntax. <br> \u2022 SSL/TLS settings need to be correct. <br> \u2022 Issues sometimes in how Sent/Drafts/Trash are addressed via path settings in NeoMutt. |\n\n---\n\n## Providers with Limitations or Lower Compatibility\n\n- **Free or minimal providers that do *not* support full IMAP/SMTP or require workarounds**  \n  Example: ProtonMail free accounts generally can\u2019t use the IMAP/SMTP Bridge; the Bridge is a paid feature. Without it, the provider may be mostly web-only. ([proton.me](https://proton.me/support/imap-smtp-and-pop3-setup?utm_source=openai))  \n- **Providers with custom or limited IMAP implementations**  \n  Some corporate or university email systems might support IMAP but with limitations (caps on simultaneous connections, restricted folders, odd behavior for \u201cexpunge\u201d, etc.). Sometimes they also require using app-passwords or OAuth. Always test these for your specific needs.\n\n---\n\n## What to Check When Picking a Provider for NeoMutt\n\nIf you\u2019re choosing a provider and want to make sure the two-way sync works well with NeoMutt, here are some verification checkpoints:\n\n1. **IMAP + SMTP access**  \n   Make sure provider offers both, with encrypted connections (IMAPS / TLS). If only POP or only webmail, two-way with flags/changes/moves won\u2019t work well.\n\n2. **Authentication options**  \n   - If provider supports OAuth2 (Gmail, Google Workspace) or app-specific passwords (Fastmail, iCloud) when 2FA is enabled.  \n   - Some require special \u201capp passwords\u201d or let you generate credentials solely for external clients.  \n\n3. **Folder management features**  \n   - Sent, Trash, Drafts \u2013 are they real IMAP folders? <br> - Uploading your Sent via NeoMutt into provider\u2019s \u201cSent\u201d folder. <br> - Be aware of how folder names map; also check hierarchy separator (e.g. \u201c/\u201d vs \u201c.\u201d vs something else).\n\n4. **Flag sync behavior**  \n   Does marking read / unread, starred, flagged get reflected immediately and reliably? NeoMutt supports standard flags; provider must too.\n\n5. **Rate limits / performance**  \n   Some providers limit how many simultaneous IMAP connections, or how fast you can sync large folders. With large inboxes or archives this can matter.\n\n6. **Paid vs. Free plan differences**  \n   Some providers\u2019 free tiers restrict external-client access (e.g. disabling IMAP/POP or forcing web apps only until you upgrade). Always check which plan includes those features.\n\n---\n\nIf you tell me what your priorities are (e.g. privacy, price, custom domains, large archive size), I can suggest a few providers that would be excellent fits for your NeoMutt two-way workflow."

Let\u2019s break down what *is* satisfied by your setup, and what you'll need to pay attention to (or accept) to get exactly the workflow you want.\n\n---\n\n## What Works Well in This Setup\n\nHere\u2019s what you *do* get by using Fastmail with bidirectional IMAP + NeoMutt + (local) MH format:\n\n- Fastmail allows IMAP + SMTP (for Standard / Professional plans) so NeoMutt can *both* fetch messages and let you send mail in a way that syncs flags, moves, deletes etc. with the server. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000278342-Server-names-and-ports?utm_source=openai))  \n- NeoMutt supports handling of IMAP folders (read/unread status, move/delete, etc.) and syncing those back to the server. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n- MH format (where each message is a separate file in a folder) is supported locally by NeoMutt for storing and accessing messages. NeoMutt can also cache headers and bodies to speed up local operations. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n\nSo with **Fastmail Standard+**, NeoMutt, and MH-format local stores, you should have:\n\n- full two-way sync (IMAP flags/folders/etc.)\n- configurable local archives in MH directories\n- ability to send via SMTP while having \u201cSent\u201d messages stored on Fastmail\u2019s \u201cSent\u201d folder\n- local speed when working with archives (MH + caching) plus all remote server features\n\n---\n\n## What Doesn\u2019t Work Perfectly (or Needs Configuration / Workarounds)\n\nHowever, some things may not match \u201cideal\u201d without extra work. Here are the points to consider:\n\n1. **Keeping MH store in sync with remote IMAP in a live manner**  \n   Your local MH folder won\u2019t automatically reflect remote changes unless NeoMutt is connected and synced. If you make changes elsewhere (say via a phone), you\u2019ll need NeoMutt to fetch and sync again so that your local MH copy lines up.  \n\n2. **MH isn\u2019t native \u201cfolder mirrors\u201d**  \n   MH is for **local storage** of messages and isn\u2019t a mirror of remote IMAP. NeoMutt caches / saves local copies but remote server state (folder hierarchy, flags) is still authoritative. The local MH archive is something you manage; you\u2019ll need to adopt conventions or scripting if you want every remote folder duplicated locally in MH format.\n\n3. **Consistency / duplicated copies**  \n   If you archive (move) messages remotely, but still have old copies locally, you might end up seeing duplicates, or need to clean up local MH folders manually.\n\n4. **Storage overhead**  \n   Having local MH copies of large archives plus remote server storage means using more disk space. Depending on mailbox size, you may need to manage which MH folders you store locally.\n\n5. **Sent / Drafts folder flow**  \n   You need to configure NeoMutt so that \u201cSent\u201d, \u201cDrafts\u201d, \u201cTrash\u201d etc. are mapped to Fastmail\u2019s IMAP folders, or else local and remote copies can diverge. If you misconfigure, you might have outgoing messages locally stored in a folder that\u2019s not reflected remotely.  \n\n6. **Fastmail Plan Limitations**  \n   IMAP/SMTP access is **not available** on the Basic plan\u2014only Standard and above. So you'd need to check which plan you are on. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000278342-Server-names-and-ports?utm_source=openai))  \n\n---\n\n## Summary: Will It Give You *Everything* You Want?\n\nYes\u2014with caveats:\n\n- If by \u201ceverything\u201d you mean *remote \u2194 local flag/folder sync*, *sending via SMTP with remote \u201cSent\u201d folder*, *archives stored locally in MH format*, *ability to work offline + online*, *private/custom domain support*, *good performance* \u2014 then Fastmail (Standard/Professional) + NeoMutt + MH will cover almost all of it.\n\n- The parts you won\u2019t get \u201cfor free\u201d are things like perfectly automatic local-remote sync of archives unless manually maintained, some possible duplication, and the requirement to ensure everything (folders, \u201csent\u201d, etc.) is configured properly.\n\n---\n\nIf you like, I can help build a precise config you can drop into `~/.neomuttrc` (or similar) that sets everything up: remote Fastmail folders, local MH storage, syncing flags, sent folder, etc., so you end up with as close to \u201ceverything\u201d as possible. Do you want me to put that together for you?"
