We block mail relaying at our SMTP gateway. So does having fw-1 check the destination domain have any value-added features? Is it another layer of defence, or a waste of fw-1 resources?

DNS does not handle this issues (SPAM), professional MTAs like MIMESweeper, sendmail or qMail behind your firewall do. I.e. in sendmail you just have to enter "OURDOMAIN" into the acces.db. I personally prefer having a single point (the mailserver oder relay) doing all the SMTP-related actions. This makes troubleshooting a lot easier and saves your firewall rescources. --Joerg http://www.firewalls-illustriert.de -----Ursprüngliche Nachricht----- Von: Christopher Collins [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 30.

Wouldn't DNS handle this issue, as you would never get a HOTMAIL.COM email to your YAHOO.COM email server?
