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:
|
|
