OK guys....I took all y'all said and did this.
1. I exported my rules from TMG.
2. I did a brand new installation of the operating system and made sure no
antivirus stuff got installed.
3. I installed the new Beta 2
4. I imported my old rules
About 24 hrs later, it did it again. It turns out that I don't think its
just SMTP its blocking...its all DNS requests too. I can teminal server in
(using the sever's IP address), restart the TMG service and WHAM...it starts
resolving DNS and letting SMTP stuff on in.
A few errors come up but nothign that seems related.
