#3010: Postfix unable to connect to IPv6 SMTP servers

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
main.cf (short-term fix) but in general it would be good to enable ipv6 on
osgeo6 (maybe after #2823 ?).
