        "content": "You're seeing the behavior you describe because of how NeoMutt handles MH mailboxes, and how it interprets the deletion mechanism when you use the `d` key. The MH (metadata-housing) format is different from Maildir, and `set_maildir_trash = yes` doesn't apply to MH mailboxes. Here\u2019s a breakdown of what\u2019s happening and how you might configure things to behave more like you expect.\n\n---\n\n## 1. What MH mailboxes do by default on delete\n\nWhen NeoMutt is working with MH folders:\n\n- Pressing `d` marks a message as **deleted**, but it doesn\u2019t move it to a \u201cTrash\u201d folder.\n- Deletion in MH means **renaming** the message files by prefixing them with a comma, e.g. `123` becomes `,123`. ([neomutt.org](https://neomutt.org/guide/advancedusage.html?utm_source=openai))  \n- Messages marked in this way are hidden by NeoMutt (ignored) unless you explicitly purge them. ([neomutt.org](https://neomutt.org/guide/advancedusage.html?utm_source=openai))  \n\nThus, \u201cdeleting\u201d under MH is more like \u201cmarking invisible\u201d rather than \u201cmoving to trash.\u201d So `set_maildir_trash = yes` does nothing here, because it only affects Maildir mailboxes. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n\n---\n\n## 2. Why `set_maildir_trash = yes` doesn\u2019t help with MH\n\nFrom NeoMutt\u2019s documentation (the \u201cdelete_untag\u201d / \u201cmaildir_trash\u201d settings area):\n\n- `maildir_trash` **only applies** to Maildir-type mailboxes. If you\u2019re using MH, NeoMutt won\u2019t move files into a \u201cTrash\u201d folder; it will instead rename them with that comma prefix as MH semantics require. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))  \n- MH messages are removed (i.e. renamed) but not really deleted unless you purge, or use `mh_purge` if it's set. Otherwise they remain with comma prefix, but that's \u201cdeleted\u201d as far as MH is concerned. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n\nSo if you want \u201creal\u201d trash behavior (i.e. message moved to a Trash folder), MH by itself doesn\u2019t support that in the same way.\n\n---\n\n## 3. How to get \u201cTrash-folder behavior\u201d with MH or change formats\n\nIf you want delete (`d`) to move messages to a Trash folder, you have a few paths you could take:\n\n### Option A: Switch from MH to Maildir\n\n- Convert your mail storage to *Maildir* format instead of MH.\n- Then `set maildir_trash = yes` + `set trash = +Trash` (or whatever your Trash folder is) will work to move deleted messages into that Trash folder. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n\n### Option B: Emulate \u201ctrash folder\u201d using IMAP + synced local store\n\n- If your MH folder is being synchronized with Gmail (via `mbsync`, `isync`, or similar), another method is to use Gmail\u2019s `[Gmail]/Trash` IMAP folder.\n- Configure NeoMutt so that deleted messages are flagged or moved into that IMAP trash folder when quitting or using purge commands. Sometimes setting `trash = +[Gmail]/Trash` helps. ([futurile.net](https://www.futurile.net/2025/05/20/neomutt-mirror-imap-mbsync-tutorial/?utm_source=openai))\n\n### Option C: Use MH sequences or custom commands\n\n- MH supports *sequences* (like \u201ctrash\u201d, \u201cdrafts\u201d, etc.) \u2014 you could create an MH sequence named e.g. `Trash`, and configure NeoMutt to \u201csave\u201d deleted messages into that sequence rather than hiding them just by comma-prefixing.\n- Alternatively, map a key (instead of `d`) to a command that moves the message yourself into `~/Mail/mh/Trash` or wherever your trash directory is.\n\n---\n\n## 4. How to configure\n\nIf you decide to move to Maildir, here are some things to set:\n\n```muttrc\nset folder=\"~/Mail\"              # or wherever your base mail is\nset mbox_type=maildir            # makes new folders Maildir by default\nset trash=\"+Trash\"               # Trash folder relative to $folder\nset maildir_trash=yes            # enable moved files flagged/trash in Maildir\n```\n\nIf staying with MH and trying to simulate Trash using an MH sequence, you might do:\n\n```muttrc\n# Suppose you have ~/Mail/mh/Trash\n# Then define a key to move message:\nbind index d move to +Trash\n# Or use MH\u2010sequence:\nmh-sequence Trash           # define a sequence\n# and then use a macro or key to move to that sequence\n```\n\nCheck your MH directory structure so you have a `Trash/` directory, or whatever folder you\u2019ll use.\n\n---\n\nIf you like, I can help you write a specific `.muttrc` setup (or convert your MH setup) so that deletes go to Trash. Do you want me to build you one, given your current folder layout?"
