isync/debian

A note from isync's web site:

To use this command effectively, you need a mail client that sets the T
(trashed) flag when it deletes a message from a maildir mailbox, instead of
just removing it altogether. Currently, only Mutt 1.3.27 supports this. Without
such a client, isync will refetch the locally deleted messages from the server
since they will never get expunged. Be sure to put

set maildir_trash

in your ~/.muttrc when using Mutt.

isync can be integrated into Mutt fairly easily with a few hooks:

folder-hook ~A bind index $
folder-hook +maildir 'macro index $ "!isync -e maildir\n"'

where maildir is the name of the local mailbox (or its alias). This works well
so long as you are not modifying the IMAP mailbox outside of Mutt. However, if
you are using another mail program simultaneously Mutt will have the wrong idea
of the local mailbox flags and messages will start disappearing from its index
display (don't worry, they are still on disk).
