Yes. MAILER-DAEMON was the "From" line (no colon).
The "From:" line (with colon) had the spammer name and phone number.

Yes. And I installed this already, but, as you say, its not replyable.

I guess one thing to do is to start to reply, but
"seen finish" it if the reply-to-address evaluates
to our own domain.

Any other ideas on combating this noise?

Is there any way to not accept email unless it is replyable
while at the same time letting sender-relay mechanism know about it?
