I have used a combination of hashed directories for quick lookup and garbmail to delete any mail older than 1 month. Garbmail scans the mailbox and deletes any messages that are over N months old. It's a python script available at ftp://ftp.cendio.se/pub/misc/garbmail/garbmail-1.0.tar.gz
Using garbmail to remove old mail is the only way I've found to handle the problem of users that leave all their mail in thier box. Of course, you have to be sure everyone knows that old mail will be automatically deleted. This has also eliminated users who "can't get thier mail" which was often caused by the mailbox becoming huge and taking a very long time to scan. On Monday 24 March 2003 01:25 pm, Mordechai T.
