Exchange 2003 cannot receive from gmail and others

We recently installed KB 948963 on our Windows 2003 SP2/Exchange 2003 SP2 box.  After doing so , we cannot receive email's from Gmail and a few others.  They are not being blocked by filtering, firewalls, or anything else I can find.  We can send to them.

Intelligent message filter is off.

The SMTP log show google as starting TLS and then closing it without data being transmitted.  I assume that the AES patch we installed has messed up the communication.

Any ideas where to adjust these settings?

In Exchange 2010 you can create multiple receive connectors. I don't remember if you can do this in Exchange 2003. (This is not the same as creating an open relay ... don't do that ;-)

Some other things I can suggest:

- Are you using an SSL certificate from a third party? or is it self-generated? Could there be something wrong with it? (use the Microsoft Exchange Analyzer to check: https://testconnectivity.microsoft.com/)

- Are there any additional rollups or service pack updates you can install / reinstall?

- Have you rebooted that entire server after applying the update?

- Do you have an SPF record set up in your DNS? If not, try adding one. If you do, try testing it:  http://www.kitterman.com/spf/validate.html

- Try (temporarily) turning off any firewalls protecting that server, just long enough to see if it works. Turn it right back on after testing.
Did you check junk folders ?
Try track the message through tracking.
What about when you send messages from internal to gmail.
Did you got any NDR on gmail?
