Pop Mail times out on port 110

MacPro, Snow Leopard SERVER 10.6.2

I am having trouble in MacMail. My pop accounts keep timing out on server 110. I have verified my account setting with my email provider, have verified my system with Apple Care.

Today I deleted the pop accounts, turned OFF SpamSieve, re-set-up the pop accounts and they are working fine.

I have two other machines on this network, a Mac G5 running 10.5.8, and a MacBook running 10.6.2 (not Server) BOTH are running SpamSieve with no problems.

SpamSieve has no interaction with the POP server, so it wouldn’t be related to this problem. You might as well turn it back on.
