Postfix unable to connect to IPv6 SMTP servers

Reported by: strk Owned by: sac@…
Priority: normal Milestone: Unplanned
Component: SysAdmin/Postfix Keywords:


The postfix log has many occurrences of failing attempts to connect to IPv6 of target SMTP servers. It falls back to use IPv4 which succeeds but it's a waste of time to even try given it is unable.

osgeo6 does not have any IPv6 configuration (no address) so cannot possibly connect there

We can tell postfix to not even try, using inet_protocols = ipv4 in (short-term fix) but in general it would be good to enable ipv6 on osgeo6 (maybe after #2823 ?).
