Messages spoofed as to/from me not being scanned. What am I missing...

[Greg Deputy]

I've been running MailScanner for a little over a year now and have been
extremely happy with it.  I've had some spams getting through recently that
are addressed to me, and from me.  For some reason, MailScanner doesn't seem
to bother scanning them, just says they're clean and passes them through.
This makes me think I may have my own address whitelisted somewhere, but if
I do I cant find it.  I'm running with the spam.bydomain white/blacklists,
and have checked both the default and the one for the domain the mail is
coming in on, but my address isn't in there.  

Is there another location I should be looking for this, or is something else
going on?  The header of the message is below.

This is on a fedora core 2 system running MailScanner 4.50.15, SA 3.1.0
processing about 50k messages per day.
