Re: New kind of messages, blew right through my Trashfinder !

David,   the MX gives the incoming server for the domain. The origin ip adress (the SMTP server) can be - and often is - on another class and can legitimately change ( when the sender is roaming ) I do not think that your suggestion is possible given the existing protocols   Benoit   As you say, Randy, "From" addresses are easy to fake; but what about the originator's IP address? Could Trashfinder do an MX lookup on the domain part of the "From" address and then compare it with the actual originator's IP address? This would only be necessary for "Pass" addresses. David
