Starting on 5/11 I can no longer connect to my corporate IMAP server via AT&T GSM. I am using Versamail 2.5 and I continually receive a timeout error when trying to connect to the IMAP server.

I can use all other Internet access services, including PoP without a problem.

Our corporate IT folks swear it isn't a problem on their side and they have tested IMAP access from a variety of other devices.

Is it possible that AT&T is now blocking IMAP? Is anyone else seeing this same problem?

My guess is that the problem is due to the piece of crap called "Versamail" but I figured I'd ask just in case.

(When is Snappermail finally going to release their IMAP client?)
