As it should work. Here the mail server is not relaying. It is accepting inbound mail. It doesn't care where it's from as long as the domain exists. It is then the mailing list software that determines if the email is allowed through or not, probably based upon sender. If you connected to my mail server and said, "rcpt to: [EMAIL PROTECTED]" it would say relaying denied because my mailserver only accepts mail for a few domains. You could also say, "mail from: [EMAIL PROTECTED], rcpt to: [EMAIL PROTECTED]" and it would accept it.
