Are you rejecting at SMTP (I think that's the proper way of describing it) rather than bouncing the entire email including message body? The reason I ask is that some spammers are using servers that include the message body in the bounce as de facto relays: Spammer wants to send spam to [EMAIL PROTECTED] but wants to be untraceable (and avoid Joe's IP blocklist), so he forges [EMAIL PROTECTED] into the *from* line of the header and then mails it to a non-existent address at your domain, knowing that your server will "bounce" it all (including the message body with the spam) to [EMAIL PROTECTED] - right where the spammer really wanted it to go. My university's mail server was configured this way until it became widely blacklisted because of it. -- Mark Roberts Photography and writing www.robertstech.com
