RE: relay problems
I think this isn't a security flaw but by design, since the recipient is in the domain the server is responsible for it accepts and sends the mail. Your server does not appear to allow relaying outside your domain, which is good. It would be a bad thing if it would accept rcpt to: [EMAIL PROTECTED] when helo is sent from outside your domain. I am not sure about this, but i think that if you would block this you are not gonna be able to receive mail at all.
