Oh, and one more thing...
If you allow non-mail server port 25 traffic to be sent from within your
network, you either want to block that entirely, or ensure that it
doesn't go out from the same IP address as your mail server. I have
seen many of my clients end up on lists like XBL because of an infected
desktop that was NAT'ed to be sent from the same IP as their mail server.

Hi All,
Has anyone figured out how to stop Yahoo from blocking email? They've
blocked all email from our servers for about 3 weeks. I've submitted their
forms but it hasn't done any good.
