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 www-d...@www.some.hackedsite.com . 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)
