Ah, you're right.  Sometimes one loses site of the forest for the trees.

Well, spam/viruses *shouldn't* be any of our problem and if they brought
back public tar and feathering it wouldn't be <g>.  But it is.  So I'm
just looking for the easiest way to ride out this storm.

Not really - a one line entry in spam.blacklist.rules is pretty simple,
and would solve the immeditate problem until I can get milter-ahead or
some other more robust solution implemented.  Not as optimal as doing it
at the MTA perhaps, but definitely a testimony to the flexibilty of
MailScanner!  Syncing active directory and sendmail is certainly doable
but it's not a five minute job.

Question is, would the example I gave work, and if not, what would?

Thanks, you too.  And a spam-free New Year...
