Hi all, I have a client thinking of setting up a mail server in his office, as well as a backup system. I set up something similar to this for another client using RH, and a lot of help. His hosting is currently with Blue Genesis, and his in office internet connection is through Sympatico. Since he does not have a static IP, would it be difficult to set up a mail server for him? I figure if I change the zone file for mail to a dynamic DNS program on the server, he will be able to use pop/smtp connects through the server. How would that work since the domain and the mail are going to different places? Also, as far as backup goes, can I do an rsync to a whole bunch of Windows machines (XP, NT, 2000, 98, 95, ME) and then do comparative backups at intervals? Any help is really appreciated, Sid
