Wietse explained this a few weeks ago: /etc/postfix/transport: example.com smtp-ipv4-only: example.net smtp-upv6-only: /etc/postfix/master.cf: smtp-ipv4-only unix - - n - - smtp inet_protocols=ipv4 smtp-ipv6-only unix - - n - - smtp inet_protocols=ipv6 /etc/postfix/main.cf: transport_maps = hash:/etc/postfix/transport Execute "postmap hash:/etc/postfix/transport" and "postfix reload" when the transport map is changed. http://www.postfix.org/postconf.5.html#inet_protocols -- Best regards, Manuel
