Administrivia: new list server

[Damien Miller]

Hi,

I've migrated the list, bugzilla and anongit servers. With one exception
(below), you shouldn't see any difference. If you do then I've messed up
and I'd appreciate your letting me know.

The list server now runs on different MTA that turned out to be
subtly incompatible with the TMDA mail filtering software that
provides the ability for non-list members to post to openssh-unix-dev,
so I've disabled non-member posting until I can sort it out.

Thanks,
Damien Miller
