Hi, I must have been searching at the wrong place or using the wrong keywords as I have been trying to find how to correctly transport to a particular smtp relay or have postfix do a MX query based on the "from" address field. I did look at the postfix doc, in se's and the postfix-users archives withtout any luck. The transport maps do a great job of doing it based on the "to" address field or domain but I am still looking to find how to do it with a "from" field. I hope someone can point me to the right doc.
