We've been using Maildir with courier-imap on some reasonably large systems with excellent results. Of course one must be sure that the file system(s) involved have sufficient capacity to handle the expected load. Maildir has been very effective at ISPs where customers may not be checking their mail, or otherwise have rather ancient stores. If the ISP's policy states that mail older than N days will be removed, then a simple find can clean out the old mail: find /home/*/Maildir -type f -mtime +$N | xargs rm Bill -- INTERNET: bill@Celestial.COM Bill Campbell; Celestial Software LLC UUCP: camco!bill PO Box 820; 6641 E.
