I'm not sure if I'm right with this: Should it be possible to determine a list of IP-ranges from the real outgoung smtp-servers of this popular domains, then Declude probably can add a new test if this mail (using a popular from domain) commes from one of this ip-ranges.
Even if this ip-ranges are very wide (Class C or B) a lot of spamming servers forging the recipients adress should be caught.
