If everything keeps working with no errors, then I think enabling this by default is probably ok. If not, then I'd be concerned that this violotes the charter for -stable.

A machine with a non-IPv6 enabled kernel which uses the new configuration will get a syslog informational report when they start the daemon saying the optional socket was disabled but the MTA will continue to operate normally: Dec 31 21:06:23 scooter sm-mta[2184]: starting daemon (8.12.10): SMTP+queueing@00:30:00 Dec 31 21:06:23 scooter sm-mta[2184]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon IPv6: can't create server SMTP socket: Protocol not supported Dec 31 21:06:23 scooter sm-mta[2184]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon IPv6: optional socket disabled

In -current, it affects sites without IPv6 by causing annoying messages like the following: Dec 25 22:19:30 gamplex sm-mta[507]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon IPv6: can't create server SMTP socket: Protocol not supported Dec 25 22:19:30 gamplex sm-mta[507]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon IPv6: optional socket disabled Bruce
