Praetor Questions Go to Praetor FAQ: Exchange
Go to Praetor FAQ: Domino
  Why are messages from common domains like "Yahoo" or "AOL" tagged as "REJECTED"?
 

While the display shows an address from YAHOO, AOL or many other innocent domains, spammers can easily forge this information. 

The actual originating address is far from innocent.  Often the reason for rejecting an email is that Praetor's examination of the message header determined that the actual originating address is found on a DNS Blacklist.
