It's installed on one of my backup mail servers where a lot of
the spam seems to come in on, so I'll know in a day or so if it
is working.  I did make one change:  For the
	list "friends" from ...
specification, I used some regular expressions to specify the
list members.  e.g.:
	/.*@foo\.com/
intending to allow mail from anyone in the foo.com domain.  It
did not complain on startup, so I presume it knows how to deal
with these constructs correctly within a list.

I'll report back in a day or two with the results.

Thanks again,
Rob
