550 5.7.1 Message rejected as spam by Content Filtering Exchange 2010
One solution is to add the senders email address to the exception list in content filtering properties.
1. Open EMC
2. expand OC
3. Click on Hub Transport
4. Anti Spam tab
5. Right click on Content Filtering
6. Exceptions tab
7. ender and add senders email
I don’t recommend this if exchange is the only spam filter because spammers can spoof the from address.
