I did not get this solution started in the proper direction -- sorry. I believe the following solution is closer:
main.cf: sender_dependent_relayhost_maps = regexp:/etc/postfix/sender_relay.regexp sender_relay.regexp: /@raystedman\.org$/ [smtp-relay.gmail.com] This should relay email where the from email address contains the domain @raystedman.org to smtp-relay.gmail.com. I need this relay to use a specific ip address to separate bulk and transactional email onto different ip addresses. How can I accomplish this?
