Part II - Spam Protection Exceptions

Hi everyone, I'm back with more information.

This time I wanted to touch base on 'exceptions' in Exchange 2003.

Id suggest reading part one on how to setup the realtime spam protection first; Then this will go nicely for step 2, setting up your 'exceptions'.

Exceptions in Exchange 2003 is a surefire way your email sender will get through if their email server is blocked.

To configure Exceptions, in Exchange 2003 Management,
goto > (root) Global Settings > Message Delivery >
Right-click properties.

Then goto > Connection Filtering tab, there should be an 'exceptions' button.

I ran into the problem where some users complained they couldnt send from aol, and yahoo and a few other ISP's that were notoriously large, and well unfortunately were listed on a blacklist for some reason or another.

So.. I added their SMTP Server to my exceptions list, and just kept close monitor on their usage. I didnt notice any spamming from the domains in my time monitoring.

But for everyones pleasure I've listed my exceptions,
I had to add each of these in order for the users from the domains could send. Each of these ISP's are listed in some blacklist for some reason or another. I had added them for convienance sake, so I didnt have to bother adding EACH sender..
