Spam Filter blocking all domains Exchange 2007
Posted on 2010-01-05
We have Exchange 2007 running on only one server in our enterprise. Our MX is pointed to our IP. The problem we are experiencing is that after enabling the spam filter, senders that previously could send messages to us are getting rejected as spammers. This is even occuring with senders on the big networks, ATT, Comcast, Yahoo, and AOL. True spam is going right through the spam filter. I believe this is because the Content filter is not being applied and is a separate issue altogether. I am at a loss as to why we are blocking legitimate domains. Any help you can give to resolved this will be much anticipated.
