I cannot send through my company's server when using my new ATT wireless router from home. All other locations seem to work fine. Is there a setting required?
Using port 1025 currently. Connection security set to none. TWTC is the host and I have checked with them and am able to send/receive email fine using webmail, just cannot send mail using T-bird. I can receive. Their advice is to contact T-bird.

I'd suggest you talk to your corporate IT folks.
Thanks for suggestion, but that is where I started. He sent me to TWTC, TWTC sent me to T-bird because everything works on their end. The conflict must lie between ATT (my home wireless) and T-bird because I can send/receive everywhere else just fine.
Is your corporate server reachable from the public Internet?

Yes, the server can be reached normally. I am at work right now so unable to reproduce the problem to see the troubleshooting info. Will try to post that tonight. Thanks!
ATTblock port 1025 nationwide. I suggest you thank ATT for their incompetent support and go see your work IT people about them provisioning another port for you to send mail on. Noting that ATT will not allow TCP ports 135, 139, 445 and 1025.
Otherwise have them assist you in setting up a VPN to access your work email server.
