Hi! 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.
