I had a problem with postfix on a mailserver that we used for "member communications". Many, many bounces as the list got more stale. These bounces would "fill up" a mailbox.
Solution we found, in main.cf: mailbox_size_limit = 1073741824 Prior to this setting, postfix had some ridiculously low idea of how big a mailbox should be allowed to be (at least for this application). Hope this is helpful. -- Jack Bates Venice, CA, USA I play Texas Hold'Em at http://www.fulltiltpoker.com
