Hi, I have a postfix-3.5.10 system and am trying to process mail prior to it being forwarded to another domain that has multiple MX records. Many years ago I used fallback_relay in master.cf but now it appears to be referenced as smtp_fallback_relay?
I don't understand the syntax for adding multiple relays and whether I'm even doing it the right way. master.cf: orion unix - - n - - smtp -o smtp_fallback_relay=192.168.10.10,192.168.11.11 relay_domains = $mydestination, example.com, example1.com transport: example.com orion:192.168.9.9 Also, on a somewhat related note, is it possible to configure a transport for relay_domains and a separate transport for virtual_alias_domains?
