[Mimedefang] Blacklist vs Access_db

[Mycrom]

Spamassassin can only view and evaluate your headder "From" address as it
just scannes the message body (The one you see in your e-mail client when
you open the message). Only the MTA's in message transmission keep track of
the real envelope "From" address.
