I will be taking the client mail server down for maintenance just after midnight to image it for recovery in the event of file system corruption.  This should take less than about 25 minutes.

During this time, pop, imap, outbound smtp, and webmail will be unavailable.  Incoming mail will still be processed.  Mail can be viewed and/or deleted using shell mailers like pine, mail, mush, mh, but outgoing mail can not be sent during this time.  Some mailers that use the local mail smtp server will queue, but any that try to send via mail.eskimo.com will fail.
