No, such a check is not possible.
At least it would be not easy to setup such a feature, because most times
you'll need alot of exeptions - for example combination (and's and or's)
of user names, sender domains, IP's , receipients ..... and there
negations.
I think, if a spammer uses such a fake he will make other mistakes, which
will be detected by assp.

Betreff: [Assp-user] Match sender username to recipient
I have been seeing a massive amount of spam--at least 95% (for the past
few hours it's 100%)--where the fake sender's username matches our
recipient's username EXACTLY. For example:
FROM: [email protected]
TO: [email protected]
Often the domain is foreign. Obviously fake (except in the very rare
condition where Bob or his friend has the same username at an entirely
different domain/country).
Is there a way in ASSP to test sender vs. recipient usernames? And
preferably score it?
