Is there a way in Postfix, similar to the transport table, to specify different transports for outbound mail based on a recipient mail server?
In other words, if xyz.com is a large mail hosting provider and it's determined that user@destination.com relays through mx-01.xyz.com, can I configure Postfix to send all *.xyz.com-bound messages through Amazon SES instead without having to enumerate all the possible recipient domains?
Thanks!
