Thanks. However, in many cases these are actually getting through.
Since the ip address of the sending server isn't the spammer and isn't
in the RBLs those checks aren't as helpful as they would've been for the
I tend to think these aren't being sent by a spammer who's identified a
particular server with the specific intention of using the DSN for
delivery, but rather just by a worm that's using my domain addresses as
the faked sender address. If a specific server had been targeted, it'd
probably end up in a DNSBL. SPF would help with the original message,
but of course it does nothing to help with the bounce.
