Im using postfix+postfixadmin+mysql+courier-imap
i just implemented pop-before-smtp[1], my problem is after recieving the mails i connect to the server using telnet and try to send spam using
the
mail server it did send it didn't ask for authentication anymore. i'm
not
sure how this pop-before-smtp really works but i was thinking how should
i
secure the server in this kind of attacks.
Generally speaking, pop-before-smtp was (and is) a big hack. The right answer is to set up SMTP-Auth.
