So apparently on my system—qmail as per qmailtoaster.com—it is by design not to include the rDNS hostname in the "Received: …" header. See my discussion on the QMT list: <http://www.mail-archive.com/[email protected]/msg38313.html>.
So that degrades SA performance huh? At least it's configurable, I'm going to enable lookups and see what happens. Quinn
