SPAM by same email as recipient?

Also do NOT whitelist the domains you serve in MailScanner.conf (is
definitely not spam) or spamassassin

Also having the list of any rules hit is always useful in the headers so
you can see why it's getting through.. (or not)

I always add the SA info into email headers to see what the score and rule
hits are ( helps with debug), in MailScanner.conf make sure the follow are
set thus:

Spam Score Number Format = %5.2f

Detailed Spam Report = yes

Include Scores In SpamAssassin Report = yes

Always Include SpamAssassin Report = yes

Spam Score Number Format = %5.2f
