[NBLUG/talk] disabling mail on account

That's actually what I tried. I set up an alias in /etc/aliases that pointed to a non existing user "invaliduser". Then I tested the server by sending a test mail. The server took the message and then returned a bounce message a few seconds later. In the case of spam the bounce message would go to some innocent person somewhere or in turn be bounced by that mail server generating a bounce message that I or some other postmaster in turn gets annoyed with. Rejecting at smtp is best. Quietly dropping it is almost as good.
I'm probably going to have to do the whole m4 thing to get this server to do what I really want. Going to /dev/null is at least workable though. I don't have to worry about spam piling up unwatched and scratch my head over all the hard drive space taken up.
