> Is there any possibility to warm about something which looks like faked ? It's pretty difficult to do this accurately. SpamAssassin has some rules that look for obviously-faked headers; the MIMEDefang slides have some suggestions for detecting obviously-faked HELO arguments. However, all of these rules can have false-positives. They also fall into the realm of "policy" rather than "mechanism", so they are not built into MIMEDefang by default.
