Got a bad AOL Address or any email address?

A client emailed today with a question on filtering an email address. The CEO was getting over 3000 msgs from an old email address of a legit business. Why do these seem to always be AOL addresses? OK so anyway the question was, "How can you stop this one email address?"

Well here's how:
In Exchange Manager go to the System Manager and expand Global Settings.
Right click Message Delivery and then choose Properties.
Click the Sender Filtering tab and click add to add the bad email address in.

Now remember that you are only half way done. Some do the above and then don't see any results thus getting frustrated with Exchange. Why? They haven't enabled the filtering on their SMTP Virtual Servers.

In System Manager expand Servers and the Server you're working on. Expand Protocols, SMTP.
Right click the SMTP virtual server.
On the General tab, click Advanced.
In the Advanced dialog box, select the IP you're using. (Most times for SBS it's All Unassigned) And make sure that the Apply Sender Filter is selected.

There you go. NOW it works. And by all means if you're a business with an AOL address, step up to the plate and get SBS, please!
