I find a lot of spam is rejected on that simple filter. It is amazing how much spam does not have a valid domain listed on the return path....
Since all your mail is being forwarded on to your Exhange server (which should have rules in force prohibiting relaying) I would not worry about having the "relay for clients only". Another way to do this is to have the "relay for clients only" checked but then have a rule in your router of the form: mydomain.com = mydomain.com.smtp This is how you setup SIMS as a secondary for mydomain.com and simply tells SIMS to send all mail for that domain directly to the SMTP sending functions and not worry about local clients for it. ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
