I would like to block certain addresses from receiveing email.
My understanding is all I should have to do is put their email address in /var/qmail/control/badrcptto, save the file, and qmail should then bounce back to the sender. But it doesn't work. I've even restarted qmail to no avail.
Anybody have an idea what I'm doing wrong?
Yes, I know, I should be editing a templates fragment, but this is only for short term and so is not worth the effort.
