In the previous state, postfix would still try to use IPv6 addresses, even when it is disabled in the global networking config. Cf. https://www.postfix.org/postconf.5.html: With Postfix 2.8 and earlier the default is "ipv4". For backwards compatibility with these releases, the Postfix 2.9 and later upgrade procedure appends an explicit "inet_protocols = ipv4" setting to main.cf when no explicit setting is present. This compatibility workaround will be phased out as IPv6 deployment becomes more common. inet_protocols = ipv4 inet_protocols = all (DEFAULT) inet_protocols = ipv6 inet_protocols = ipv4, ipv6 So setting it to 'all' conditionally does not help, as we are now on version 3.x. |
