Autoexpunge not working for Junk?

[Amir Caspi]

Hi all,

	I set up dovecot a couple of months ago and am having trouble getting autoexpunge=30d to work on my Trash and Junk mailboxes.  Not sure why not because I'm not getting error messages in my log.
	Running "doveadm search -u <user> mailbox Junk savedbefore 30d" shows me many messages (I've got messages back to mid-May, and a couple of other users have them back to early April, although if this setting were working, there should be nothing earlier than June 24).  Running a manual doveadm expunge works fine... it's just autoexpunge that seems to not be running at all.

I'm using sendmail as the MTA and procmail as the LDA, so dovecot is running purely for IMAP/POP service.

Any help is much appreciated.

Thanks!
