Part of the responsibility of being an administrator is knowing about these things, mail relays, etc... this is fundamental. I also would suggest using qmail, or even Postfix, as they, out of the box, do not allow relaying at all. One does not need to know anything about programming to understand the concepts of mail relaying or protecting your system. One other thing to check, if you run a web server, is to check in your CGI directory if you have a formmail CGI. If you do, get rid of it. The older versions of this is exploitable and spammers use this to relay mail instead of using your MTA. -- Best regards, Gary How do you tell when you run out of invisible ink?. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
