To block open relay servers.

There is no particularly good reason, honestly. About the only reason to do so is if a host is compromised, and the attacker wants a standard promiscuous relay. Relaying can nonetheless be done on a compromised host, as the method of injecting the messages need not take place over port 25.

•It is (and has always been) a violation of the TOS
•It helps contain access to open-relays to within OOL netblocks, preventing use from outside OOL.
•Combined with forced use of OOL's mail relays for outbound SMTP helps OOL identify both Spam sources as well as those running SMTP servers as open-relays.

Rochester, NY		 I use : smtpport.com . So far no compaints! It'll take a random high port to a lower port on any server you choose.
