This needs an inet_interfaces setting that DOES NOT CONTAIN 'all' and that DOES NOT INCLUDE the IP address of the postfix1 instance. After changing inet_interfaces, do "postfix stop". > ++++++++++++++++++++ > > The postfix1 instance main.cf: > ++++++++++++++++++++ > inet_protocols = ipv4 > multi_instance_group = outgoing > multi_instance_name = postfix1 > myhostname = mail.example2.com > mydomain = example2.com > myorigin = $mydomain > inet_interfaces = all This needs an inet_interfaces setting that ONLY CONTAINS the IP address of the postfix1 instance.
