Hi everyone,
I haven't played with relay servers much. I really thought there was a "RELAY_README" but I find no README files with "RELAY" in them at all. Hmmm. Where can I get the basics? Specific questions I had were if I can use the standard DNS "load balancing" (multiple MX records, same priority, possibly multiple IPs resolving to one A record) setup *behind* a relay server (those MTAs behind the relay only being available via the relay and never directly). Also need to make sure I know how address verification works when ideally the relay doesn't have access to the list of (virtual) users. And assuming I can run postscreen on the relay and not need to do much connection, client and RBL filtering on the main MTAs (except address related since the relay won't have access to local addresses). Thanks a lot for any pointers.
