To amend that (with mostly historical and not so helpful info), notmuch
used to have the ability to sync the "deleted" tag with the T
("trashed") maildir flag (with maildir.synchronize_flags option
set). Other mail clients or offlineimap were then able to delete the
mails locally and/or on a server. However, this too had some issues
(concerning multiple files with the same message-id) making it
potentially dangerous, and was removed [1]. Whether this feature ever
makes a comeback depends on someone tackling the problems. And taking
into account the fact that current users of the deleted tag probably do
not expect the files to be actually deleted.
