After update to 7.3 beta mail filtering stopped working. I then went ahead and installed 7.1 RC and then configured for mail filtering again for my exchange server.

I know all i have to to do is install smtp from market and configure smtp with domain and then ip address also change the mail domain to use different domain than domain i am trying to filter. Then open port 25 threw firewall. I still have clearos 6 as a virtual machine and the filtering works.
yesterday my filtering was working so the updates install on the 26th are causing the problems.
If i port forward port 25 to my email server and close the 25 port on incomming than my email works fine.

Has anyone else had this problem?

Thanks Sam
