In that case you should be able to replace this: /etc/postfix/main.cf: transport_maps = mapping from example.com to smtp:mailhub.example.com relay_domains = example.com relay_recipient_maps = list of "good" recipie...@example.com with: /etc/postfix/main.cf: transport_maps = mapping from example.com to smtp:mailhub.example.com relay_domains = example.com virtual_alias_maps = mappings from external-u...@example.com to internal-user(s)@example.com Unless I am missing something obvious (in which case Victor will helpfully point out what's missing).
