I'd not seen any spam.  So I looked in my SpamAssassin
folder ( > 5.0 but < the reject threshold).  Lo!  There was a bunch
of spam (including, ironically, a bunch of "MS Security Patches").

Who I'm subscribed as != who I post as.

My subscription address doesn't look like it's been snorked.

Procmail looks and if the Sender: is the netbsd list's sender
and a couple other things match, it goes into my NetBSD folder.

Other things to that address get looked at with more suspicion.
