Have these machines connected to the mail server before or are they new installs?
If they are new machines with XP Pro you need to check and see if the built in firewall is enabled on the LAN port. Microsoft started shipping all of their OS restricted; this is especially true with 2003.

Imail Professional 8.11 (all patches, etc...). All of a sudden certain (brand new) machines cannot connect to the server. This is all on a LAN, dedicated IP range in the DHCP scope that hasn't changed. I try to telnet to SMTP on port 25, nothing. Outlook can't connect to SMTP or POP3. I've checked my sys* log files, nothing there, doesn't even show the connection attempt. Any ideas? The individual machines have no other connection problems, and everyone else on the LAN is working fine.
