Subject: trash-folder
With this patch, if the trash variable is set to a path (unset by default), the
deleted mails will be moved to a trash folder instead of being irremediably
purged when syncing the mailbox.
For instance, set trash="~/Mail/trash" will cause every deleted mail to go to
this folder.
Note that the append to the trash folder doesn't occur until the resync is
done. This allows you to change your mind and undo deletes, and thus the moves
to the trash folder are unnecessary.
Notes
* You might also want to have a look at the purge message feature below
which is related to this patch.
* IMAP is now supported. To retain the previous behavior, add this to your
muttrc:
folder-hook ^imap:// 'unset trash'
FAQ
Every once in a while, someone asks what are the advantages of this patch over
a macro based solution. Here's an attempt to answer this question:
* The folder history doesn't clutter up with unwanted trash entries.
* Delayed move to the trash allows to change one's mind.
* No need to treat the case of "normal folders" and trash folders
separately with folder-hooks, and to create two sets of macros (one for
the index, one for the pager).
* Works not only with delete-message, but also with every deletion
functions like delete-pattern, delete-thread or delete-subthread.
To sum up, it's more integrated and transparent to the user.
* Patch last synced with upstream:
- Date: 2007-02-15
- File: http://cedricduval.free.fr/mutt/patches/download/patch-1.5.5.1.cd.trash_folder.3.4
* Changes made:
- Updated to 1.5.13:
- structure of _mutt_save_message changed (commands.c)
- context of option (OPTCONFIRMAPPEND) changed (muttlib.c)
- Fixed indentation of "appended" in mutt.h.
