Hi, I have this software which periodically sends out email notifications, but unfortunately the mail format is not RFC-compliant. These mails are sent out using an Exchange server #1, with the recipients of domain xyz.com on Exchange server #2. There is a qmail server between these two Exchange servers. Unfortunately the qmail server blocks the mail due to its non RFC-compliance. My question ... is there a way for Exchange to rewrite the incoming mail headers so that it is RFC-compliant? Or if there isn't, how do I reroute the mails sent to xyz.com to bypass the qmail and to go directly to Exchange server #2? Many thanks, Mun Fai
