I don't think this is a problem of the header format, it's a problem of the transmitted information. The Received: header format is up to the receiving MTA, what ends up there is a problem of the sending MTA, and this is what I'm trying to do. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
