        "content": "If you're planning to use NeoMutt (or nmh or similar text/UIs) on a Linux box for email with syncing, there are a few providers that are more friendly than others. I'll break it down by provider, outline what's tricky (especially around authentication), and give some tips. By \u201csyncing\u201d I mean properly using IMAP (or POP in rare cases), supporting SMTP for send, handling folders/mailboxes, and dealing with modern security (2FA, OAuth, app-specific passwords, etc.).\n\n---\n\n## What NeoMutt Supports / Needs\n\nFirst, some general capabilities of NeoMutt that affect which providers work best:\n\n- Native IMAP and SMTP support, including secure modes (SSL/TLS, STARTTLS). ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n- Multiple authentication methods: LOGIN, PLAIN, SASL, etc. Also some support (via scripts or contrib) for OAuth2/XOAuth2 / OauthBearer, but it often takes more setup. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai))  \n- Can sync mail locally either by using built\u2010in IMAP + headers/body caching or using external tools like `isync`/`mbsync`, `offlineimap`/`imapfw`, etc. ([neomutt.org](https://neomutt.org/contrib/useful-programs?utm_source=openai))  \n- Sending typically goes via SMTP, either using NeoMutt or via an external \u201csendmail\u201d\u2010like client (msmtp, etc.). Authentication and TLS are needed. ([neomutt.org](https://neomutt.org/test-doc/bestpractice/nativimap?utm_source=openai))  \n\n---\n\n## Providers that Work Best / Are Easiest\n\nThese providers are known to be relatively painless, provided you follow their settings and meet security requirements:\n\n| Provider | Why It's Friendly | What You Need to Know / Do |\n|---|---|---|\n| **Fastmail** | Highly reliable IMAP + SMTP, simple auth, good documentation, good folder/mailbox support. Users often report fewer odd quirks. | Use SSL/TLS, configure correct ports; set up with regular password + 2FA or app password as needed. OAuth may be optional. |\n| **Zoho Mail** | Has good IMAP/SMTP support. Supports enabling IMAP via settings; good docs. ([zoho.com](https://www.zoho.com/mail/help/imap-access.html?utm_source=openai)) | If you use 2FA, you\u2019ll need an **application\u2010specific password**. Also enable IMAP access in the Zoho Mail settings. ([zoho.com](https://www.zoho.com/mail/help/imap-access.html?utm_source=openai)) |\n| **Private Domain (standard MX hosted service)** with a decent host (e.g. DigitalOcean, or a mail host using Dovecot/Postfix) | Since it's under your control or near\u2010standard, fewer surprises, much like Zoho / Fastmail. If they support usual authentication (passwords, TLS) it's straightforward. | Just ensure TLS, correct ports, username/password auth, all folders visible. If using OAuth, that's a bonus but often unnecessary. |\n\n---\n\n## Providers that Are More Difficult / Require Extra Setup\n\nThese are providers that often cause friction, mostly due to security/auth changes, non\u2010standard folder names, or restrictions:\n\n| Provider | What Makes Them Hard | Common Workarounds / Fixes |\n|---|---|---|\n| **Gmail (Google Accounts / Workspace)** | Google has been deprecating \u201cless secure app access\u201d (password\u2010only IMAP/SMTP), pushing OAuth2. App passwords are required when using password auth + 2FA. Also OAuth setup with NeoMutt requires external scripts; Google\u2019s security checks can block flagrant usage. ([arcanoae.com](https://www.arcanoae.com/resolving-issues-with-gmail-and-oauth-2-0-requirements/?utm_source=openai)) | Best path is to enable 2FA on your account, generate an **app password** for IMAP/SMTP, use TLS ports (IMAPS on 993, SMTP with SSL/TLS or STARTTLS), or use the contrib OAuth2 scripts (`oauth2.py`) in NeoMutt. Note: Google Workspace sometimes requires admins to whitelist \u201capp passwords\u201d or authenticate in specific ways. ([neomutt.org](https://neomutt.org/guide/optionalfeatures?utm_source=openai)) |\n| **Office 365 / Microsoft Exchange / Outlook.com** | OAuth is mandatory in some tenants; basic auth is being deprecated. Some SMTP commands are disabled (e.g. authenticated SMTP might be turned off), folder paths can be non\u2010standard. Also, when using organizational accounts, policies often restrict access unless settings white\u2010listed. ([reddit.com](https://www.reddit.com/r/linux4noobs/comments/1pktk40/neomutt_office365_oauth_without_a_whitelisted/?utm_source=openai)) | Use the OAuth2 scripts provided in NeoMutt\u2019s contrib for Office365/Exchange. Confirm SMTP auth is enabled for your user. Sometimes you may need to use MS Graph API (less compatible with plain IMAP/SMTP clients) if basic auth is blocked. |\n| **ProtonMail** | For regular ProtonMail accounts, IMAP/SMTP is unavailable without the \u201cBridge\u201d. ProtonMail Bridge runs as a local process and makes mail available locally for IMAP/SMTP\u2010style clients, but must be installed and configured. ([reddit.com](https://www.reddit.com/r/ProtonMail/comments/hu6qv8?utm_source=openai)) | Use ProtonMail Bridge (paid plan). Then, point NeoMutt\u2019s IMAP/SMTP configuration to the Bridge\u2019s local endpoints (often localhost + special ports). Ensure the Bridge is running. Transport encryption sometimes involves self\u2010signed certs\u2014may need to accept them. |\n| **iCloud** | Folder naming conventions (e.g. \u201cSent Messages\u201d, \u201cDrafts\u201d, etc.), non\u2010standard IMAP paths; some users report issues using NeoMutt accessing non\u2010INBOX folders. ([reddit.com](https://www.reddit.com/r/commandline/comments/mea3fi?utm_source=openai)) | Be careful to discover the correct hierarchy delimiter; maybe use the iCloud\u2019s web UI or a standard IMAP client to learn the folder names. Use explicit paths (\u201c+Sent\u201d, etc.). Sometimes setting `record`/`trash` paths with full path helps. |\n| **Yahoo, AOL, some regional/small free providers** | Some don\u2019t support modern auth, may restrict ports, may have frequent service disruptions. Two\u2010Factor/Auth support and app passwords vary. Less robust documentation. | Best to test with IMAP via a simple client first (e.g. Thunderbird), verify it works, then port those settings to your NeoMutt setup. If passwords fail, look for app passwords, allow \u201cless secure apps\u201d settings (if any), ensure SSL/TLS. |\n\n---\n\n## Specific Tips / Must\u2010Haves\n\nTo avoid frustration, set these up (assuming your provider supports them):\n\n1. **Enable 2FA and App Passwords**, especially with Gmail, Zoho, etc. Many providers require 2FA before you can generate an app\u2010only password which NeoMutt will use.  \n2. **TLS / SSL for all connections**. Set IMAPS on port 993, SMTPS on port 465 or STARTTLS on 587. Plain text unauthenticated is almost universally blocked or insecure.  \n3. **Correct folder \u201cnamespaces\u201d / delimiters**. Sent, Trash, Drafts may not all have the same name; subscription management in NeoMutt (or query via IMAP) helps.  \n4. **Use external tools if needed**. For \u201csync\u201d (offline storage, fast local searching), `mbsync`/`isync`, `fdupes`, `notmuch`, etc., are often paired with NeoMutt.  \n5. **OAuth2 support**. If your provider (e.g. Gmail, Office365) requires OAuth2, you\u2019ll likely need to use NeoMutt\u2019s contrib scripts (`oauth2.py`, etc.) and register client ID/secret. This adds complexity (initial registration, tokens, refresh, etc.).\n\n---\n\n## Summary: Which Providers I\u2019d Recommend\n\nBased on everything, if you want the path of least resistance using NeoMutt + syncing + SEND/RECEIVE reliably, here are my recommendations (from easiest to trickiest):\n\n1. **Zoho Mail** \u2014 Very solid, modern, works well with app passwords, good doc.  \n2. **Fastmail** \u2014 If you can use it, excellent reliability, good performance.  \n3. **Private / self-hosted mail** \u2014 If you have control or use a competent host, tends to behave well.  \n4. **Gmail / Google Workspace** \u2014 Doable, but more work: you need to manage OAuth2 or app passwords and keep up with policy changes.  \n5. **Office365 / Exchange** \u2014 Extra policy & requirement overhead; more fiddly.  \n6. **ProtonMail (with Bridge)** \u2014 If you pay for the service and install the Bridge, it's workable; else, very painful.  \n7. **Free/older providers without app password/OAuth or modern security** \u2014 Often blocked or greatly tricky by now.\n\n---\n\nIf you like, I can pull up a side\u2010by\u2010side config summary for a few specific providers you\u2019re considering (say Gmail, Zoho, and ProtonMail) tailored to NeoMutt, to help you set it up directly. Do you want me to do that?"

After you read this, I'll suggest some decision points based on what matters most to *you*.\n\n---\n\n## Zoho Mail vs. Fastmail: Side-by-Side\n\n| Feature | Zoho Mail | Fastmail |\n|---|---|---|\n| **Pricing & Storage** | Free plan: host one domain, up to 5 users, *no IMAP/POP/ActiveSync for free*; paid plans start ~$1/user-month for Mail Lite with ~5-10 GB; higher tiers add retention, S-MIME, customizable business tools. ([zoho.com](https://www.zoho.com/mail/pricing.html?utm_source=openai)) | Paid plans only for IMAP/SMTP support with multiple tiers (Individual, Duo, Family, Business). Individual plan ~$6/month for 60 GB total storage (\u2248 50 GB mail/calendar/contacts + ~10 GB files). Business plans vary. ([fastmail.com](https://www.fastmail.com/pricing/us/?utm_source=openai)) |\n| **Support for IMAP / SMTP (for text clients / NeoMutt, etc.)** | Supported in paid tiers; free plan *doesn\u2019t include IMAP/POP/ActiveSync*. You\u2019ll need to generate an **application-specific password** if two-factor authentication is enabled. ([zoho.com](https://www.zoho.com/mail/help/adminconsole/two-factor-authentication.html?utm_source=openai)) | Supported on all plans except the \u201cBasic\u201d type which lacks IMAP/SMTP/Caldav/Carddav until you move to a proper tier. Uses app-passwords to access via IMAP/SMTP. SSL/TLS required. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/360058752854-App-passwords?utm_source=openai)) |\n| **Security & 2FA / MFA** | Zoho supports Two-Factor Authentication; if enabled, external clients must use an app-specific password. Can be enforced at org-level. Password security is good; offers S-MIME in premium plans. ([zoho.com](https://www.zoho.com/mail/help/adminconsole/two-factor-authentication.html?utm_source=openai)) | Fastmail offers two-step verification, app-passwords for non-web clients, passkey support, strong TLS (incl. TLS 1.3), encryption in transit and at rest. ([fastmail.com](https://www.fastmail.com/features/security/?utm_source=openai)) |\n| **Compatibility / Reliability with IMAP / mobile / syncing** | Some users report quirks: delayed syncing across IMAP/CalDAV/CardDAV; archive or folder visibility issues; web interface broader beasts with lots of extra services/tools. Mixed reliability. ([reddit.com](https://www.reddit.com/r/fastmail/comments/1ov7hf0/fastmail_and_zoho/?utm_source=openai)) | Generally praised for solid IMAP/SMTP behavior, consistent folder visibility, good support docs for setting up external clients. ([reddit.com](https://www.reddit.com/r/fastmail/comments/1ov7hf0/fastmail_and_zoho/?utm_source=openai)) |\n| **Features beyond basic email** | Zoho offers a large ecosystem: calendar, office suite, team collaboration, chat (Cliq), AI assistant (Zia), etc. If you use more than email, there\u2019s a lot there. ([zoho.com](https://www.zoho.com/mail/pricing.html?utm_source=openai)) | More focused on email, calendar, contacts, files, privacy, masked email, shared/alias addresses, custom domains. Less bloat; more polish. ([fastmail.com](https://www.fastmail.com/pricing/us/?utm_source=openai)) |\n| **Custom Domain / Alias / Catch-all Support** | Yes. Paid plans allow custom domain, aliases. Catch-all works (with some limitations) even under some paid plans. Free plans are limited. ([zoho.com](https://www.zoho.com/mail/pricing.html?utm_source=openai)) | Yes. Custom domain support in paid plans; multiple addresses/aliases; catch-all behavior is well-documented. ([fastmail.com](https://www.fastmail.com/pricing/us/?utm_source=openai)) |\n| **Privacy & Hosting Location** | Zoho offers global data center choices; subject to GDPR depending on region. Decent policies. ([techradar.com](https://www.techradar.com/reviews/zoho-mail-review?utm_source=openai)) | Based in US; privacy commitments, good security controls; less choice in region (unless they\u2019ve expanded recently). If where data is stored matters, this could be decisive. ([fastmail.help](https://www.fastmail.help/hc/en-us/articles/1500000280221-How-Fastmail-provides-a-secure-service?utm_source=openai)) |\n| **Support / UI / Extras for power users** | Powerful if you use many Zoho-services, but UI is heavier, settings more cluttered. Documentation is good. For text clients and less GUI dependency, some settings may feel indirect. ([reddit.com](https://www.reddit.com/r/fastmail/comments/u87r7e?utm_source=openai)) | Streamlined, regularly praised by power users for clean interface, simple but strong support, well-documented IMAP/SMTP settings. Easier path for minimal, dependable email setup. ([reddit.com](https://www.reddit.com/r/fastmail/comments/1ov7hf0/fastmail_and_zoho/?utm_source=openai)) |\n\n---\n\n## What Matters Most for NeoMutt / nmh / Scripting / Text-Only Usage\n\nPicking between the two boils down to what you value most. Here are decision points specific to your use case:\n\n1. **IMAP/SMTP + High Reliability**  \n   If you want minimal surprise (folders always visible, sync working reliably across clients), Fastmail tends to be more consistent. Zoho sometimes has weird syncing delays or archive/folder show/hide issues in non-Zoho clients.  \n\n2. **App-Specific Passwords + Security**  \n   Both providers support them, but Zoho\u2019s free plan lacks IMAP/POP/ActiveSync, so you need a paid plan to use external clients (like NeoMutt) properly. Fastmail ensures you cannot use the regular password for text clients, which is safer.  \n\n3. **Cost per Gigabyte / Long-Term Storage**  \n   If you expect many gigabytes of email (attachments, long history), compare the cost per GB. Fastmail\u2019s standard plan gives ~50 GB mail/etc plus extra features. Zoho\u2019s higher tiers also offer good storage, but cheaper plans have limits.  \n\n4. **Custom Domains, Aliases, Catch-all**  \n   Both support them. Check exactly how Zoho implements catch-all and alias behavior with IMAP/SMTP (e.g. do you need to define aliases beforehand? how sending \u201cFrom\u201d can be set). Fastmail tends to give more flexibility here.  \n\n5. **Privacy / Legal Jurisdiction / Hosting Location**  \n   If the location your data is hosted in (or legal jurisdiction) is crucial to you, check Zoho\u2019s data center for your region vs Fastmail\u2019s US primary hosting.  \n\n6. **Extras That Might Be Nice, but Not Required**  \n   * Masked email, alias support  \n   * Shared address books, calendars if you have more than one user or want device sync of contacts/calendars  \n   * Spam filtering, deliverability (Zoho is good, but some users mention spam filtering sometimes less intuitive)  \n\n---\n\n## Verdict / Suggestion\n\nIf I put myself in your shoes (text-based Linux box, Neomutt + nmh, want sync, low fuss), here\u2019s how I lean:\n\n- **Fastmail** is likely the easier and more reliable path. Once you\u2019re set up with app-passwords, server names, and settings, it \u201cjust works\u201d with IMAP/SMTP. Less glueing together different services.  \n- **Zoho** could be cheaper if you need only a small user account and small storage, especially with their cheaper tiers. If you already use other Zoho tools (calendar, docs, etc.), tight integration might be a bonus.\n\n---\n\n## Decision Framework: What to Ask Yourself\n\nTo decide which will serve you best, try answering:\n\n- How much email storage do I think I\u2019ll use over the next few years? (If >50-100 GB, lean to plans with big storage.)\n- Do I need external client access *now*, or is it okay to upgrade later?\n- How much do I care about having data hosted in the U.S. vs Europe / privacy concerns?\n- Do I want features like masked email, lots of aliases, a catch-all, or sharing across multiple users (or is this just for me)?  \n- Am I willing to pay a bit more for a more polished setup and fewer sync quirks, or is cost the deciding factor?\n\n---\n\nIf you want, I can model the *total cost* and *setup complexity* for your specific usage (say, 50 GB, needing custom domain, using NeoMutt + offline sync tool + IMAP) with Zoho vs Fastmail. That might make the difference clearer. Want me to pull that together?"
