Still not quite there. :-) You can't enable SMTP-AUTH for all incoming mail at all, AFAIK, since sendmail will only request AUTH for requests to *relay*. Sendmail will not request AUTH for mail to be delivered locally. If you *can* require Sendmail to AUTH everything and everyone that sends mail to you, then you will only receive mail sent by your own users. Cheers, -- Rodolfo J.
