Hello!
I don't need to say, if your server is popular, you'll get a dozens of
spam too. Lately i am getting random mails from
. I am using address verification, so
they usually not coming in, cause port 25 is not open on
www.some.hackedsite.com (no MX record on www, so falling back to A, says
the RFC). But since it comes from a foreign mailqueue, they show up a
lot of times in my log (annoyingly huge amount), hence "a temporary
error in address verification" which gives 450 code.
So, is there a way (other than modify postfix source code) to drop
mails, when there is no MX records associated with the right-hand side
of the '@' (sender's e-mail domain) ? (i dont care about the A record,
spams has nothing to do with RFCs, and sane e-mail domain has an MX
record anyway)
