Cyrus does not have any inherent understanding of what the Trash folder
is... it's just another IMAP folder.
'Deleted' in the IMAP sense refers to an email that has the '\Deleted' flag
set. A subsequent EXPUNGE will remove the emails from user view altogether.
Since the emails that are contained within the Trash folder probably do not
have the '\Deleted' flag set, they will not be expunged automatically by
You could use ipurge to automatically delete messages from your users'
Trash folders. Adding something like this to the EVENTS section of your
cyrus.conf should work (please test as a typo could lead to loss of data):
purgetrash cmd="/usr/sbin/ipurge -f -d 14 */Trash" at=0301
Which purges all messages older than 14 days, in all users' Trash folders
and runs every morning at 3:01am. See the man pages for ipurge and
cyrus.conf for more details.
