This is easy if your mail stores use Maildir where each message is in a file. I have done it many times, including at ISPs with tens of thousands of e-mail accounts. We set up a new server, create the necessary accounts on it, move all DNS to point to that server so that clients go to the new one, then rsync over their old $HOME directories to the new server. It's a completely different kettle of fish if the mail stores are in single files such as the standard BSD/Unix mail stores, U.W. IMAP's binary format, etc. Bill -- INTERNET: bill@celestial.com Bill Campbell; Celestial Software LLC URL: http://www.celestial.com/ PO Box 820; 6641 E.
