        "content": "Here\u2019s an example `.mbsyncrc` (or `~/.isyncrc`) configuration file for two-way sync (mirroring) using `isync/mbsync` with Gmail. Since you said you\u2019ll use your real Gmail address `brhbrhbrh@gmail.com` and temporarily `\"my-password\"` as your password, I\u2019ll include those. You\u2019ll want to replace `\"my-password\"` with either:\n\n- a Gmail **App Password** (strongly recommended if you have 2FA enabled), or  \n- Use OAuth2 (if you prefer not to manage app-passwords), which requires a bit more setup.  \n\nBelow is a working template. After that I\u2019ll explain each section and some important caveats specific to Gmail.\n\n---\n\n```ini\n# ~/.mbsyncrc\n\nIMAPAccount gmail\nHost imap.gmail.com\nUser brhbrhbrh@gmail.com\nPass \"my-password\"\n# If using 2FA, instead use an app password here instead of your main password.\nAuthMechs LOGIN\nSSLType IMAPS\nRequireSSL yes\nPort 993\n\n# Remote store (on Gmail side)\nIMAPStore gmail-remote\nAccount gmail\n\n# Local store (on your machine)\nMaildirStore gmail-local\nPath ~/Mail/Gmail/       # change this to wherever you want the mail stored\nInbox ~/Mail/Gmail/Inbox\n\n# Channel: defines what gets synced in both directions\nChannel gmail\nFar :gmail-remote:\nNear :gmail-local:\nPatterns *                    # sync all folders/labels\n# Exclude certain folders that might duplicate or aren't needed\n# For example, you might want to exclude \u201c[Gmail]/All Mail\u201d to avoid duplication\nPatterns * !\"[Gmail]/All Mail\" !\"[Gmail]/Spam\" !\"[Gmail]/Trash\"\nCreate Both                  # create folders locally if needed, and remotely\nExpunge Both                 # deletions on one side get propagated\nSyncState *                  # remember where things left off\n\n# (Optional) Group if you have multiple channels/accounts\n# Group gmail-group\n# Channel gmail\n```\n\n---\n\n### Explanation of Key Parts\n\n| Directive | What It Does |\n|-----------|---------------|\n| `IMAPAccount gmail` | Names your account \u201cgmail\u201d. You refer to this later. |\n| `Host imap.gmail.com`, `Port 993`, `SSLType IMAPS`, `RequireSSL yes` | Standard Gmail IMAP settings: secure IMAP over TLS on port 993. |\n| `User brhbrhbrh@gmail.com`, `Pass \"my-password\"` | The credentials used to log in. |\n| `AuthMechs LOGIN` | IMAP authentication mechanism. Gmail supports `LOGIN` but with 2FA you\u2019ll likely need an app-password or OAuth2. |\n| `IMAPStore` & `MaildirStore` | Define remote vs. local storage. Local is a Maildir layout in `~/Mail/Gmail/`. |\n| `Channel gmail` | Connects the remote store and the local store under one logical \u201cstream\u201d. |\n| `Patterns *` / `Patterns * !\u201c\u2026\u201c` | Defines which mailboxes/folders/labels to include or exclude. Gmail puts many things under `[Gmail]/...`. |\n| `Create Both` | If a mailbox exists remotely but not locally (or vice versa), will create. |\n| `Expunge Both` | If you delete something locally, the deletion propagates; and vice versa. |\n| `SyncState *` | Ensures mbsync keeps track of what's been synced so it doesn\u2019t download everything every time. |\n\n---\n\n### Important Gmail-specific Caveats\n\n1. **Enable IMAP in Gmail settings**  \n   Log into Gmail in a browser \u2192 Settings \u2192 *See all settings* \u2192 *Forwarding and POP/IMAP* \u2192 ensure IMAP is enabled.  \n\n2. **App Password vs. Standard Password**  \n   If your Google account has *2-Step Verification* turned on (highly recommended), then you should generate a *Gmail App Password* instead of using your normal login password. With 2FA, Google blocks \u201cless secure app\u201d logins, which includes basic LOGIN via IMAP with your main password. Using an app password generally works fine. ([wiki.archlinux.org.cn](https://wiki.archlinux.org.cn/title/Isync?utm_source=openai))  \n\n3. **Using OAuth2**  \n   If you want a more secure setup without storing any password (even app passwords), you can use OAuth2 tokens. That requires configuring an external helper such as `oama` or `oauth2token`, or using scripts like `mutt_oauth2.py`. In the `IMAPAccount` section you'd replace `AuthMechs LOGIN` with `AuthMechs XOAUTH2` and use `PassCmd ...` to fetch the token. ([wiki.archlinux.org.cn](https://wiki.archlinux.org.cn/title/Isync?utm_source=openai))  \n\n4. **Avoiding duplicate \u201cAll Mail\u201d**  \n   Gmail\u2019s \u201cAll Mail\u201d label contains everything (including Inbox, Sent, etc.). If you sync it, you often end up with duplicates locally. Many people exclude this mailbox in the `Patterns` directive, or decide not to sync certain `[Gmail]/...` labels.  \n\n5. **Deletion behavior**  \n   Gmail\u2019s IMAP deletion doesn\u2019t always map cleanly to what you expect. There are Gmail settings (\u201cWhen I mark a message in IMAP as deleted\u201d, \u201cAuto-expunge\u201d, etc.) in the web UI under the IMAP settings. You may want to set \u201cAuto-Expunge off \u2013 Wait for the client to update the server\u201d so that mbsync can explicitly propogate deletes without Gmail immediately expunging things. ([erichgrunewald.com](https://www.erichgrunewald.com/posts/setting-up-gmail-in-doom-emacs-using-mbsync-and-mu4e/?utm_source=openai))  \n\n---\n\nIf you like, I can also generate an OAuth2-based version of this config for you, so you don\u2019t need to store any password/plaintext app password. Do you want that?"
