mail.freebsd.sol.net appears to be healthy.  A quick telnet to the smtp
port had no problems sending me a mail message.  I don't see any unusual
log messages, and no unusual kernel messages.

There's a boatload of stuff in the queue (1170 req's) but the queue is
running current stuff and the remaining stuff appears to be all
"Operation timed out"'s and "Connection refused"'s.  The number appears
to be a bit higher than usual, but I've seen it worse before.  There
may be some delays in processing such a large queue.

I'll throw mail3.sol.net into the alias too.  If anyone notices any
differences, please let me know.

Administrivia: mail.freebsd.sol.net (a.k.a. mail2.sol.net) is due
for replacement in the next month or so anyways, as part of routine
upgrades and stuff.  I'm not sure what to do about anti-relaying
stuff: I'm in the difficult position of being a proxy for a lot of
domains.  Any advice?

The machine must be able to accept mail from anywhere destined for one
of the domains that sol.net services.

The machine must be able to accept mail from one of those domains and
send it to anywhere.

I haven't seen a really good way to do this that doesn't require
maintaining access lists.
