Hi all, I want to use DSPAM and Postfix as a relay (point MX records to the relay and Deliver the Mail to the real Mailserver). If I follow the instructions of the relay.txt I get a 451 "Temporary lookup failure" If I define the domain in virtual_mailbox_domains. I have no glue how to solve this.
My old setup worked with transport maps and I wonder where I should write the destination url now. My old config did this with transport_maps (example.com [mail.example.com]). Any suggestions? regards Sven
