Which is the way it's supposed to work. SMTP-AUTH makes a user login using a username and password (which are an existing account on your system) before sending emails. What you're trying to do (or asking to do) would stop your server from receiving emails from everyone else. How could I send you this message, if I had to SMTP-AUTH in to send it? I do not have an account on your machine, so I would have no valid user/password to login to send the message. If you're looking for your server to send emails, but never receive them, you'll want to firewall the port for export only. If you're looking to get rid of the messages to bad emails on your domain, set it to bounce for the catchall account. CHKUSER will then kick in, and then someone "telnets to your machine" and send an email to [EMAIL PROTECTED], it will drop the connection on them. This will stop the bad spammers from throwing hundreds of emails at you.
