[ADMIN] Issues with new linux-mips.org machine

[Ralf Baechle <ralf@linux-mips.org>]

As you probably noticed there were a few kinks after last week's migration
to the new machine, in particular the spam filter was somehow a little
generous in what it allowed through.  This may need more fine tuning but
one of the issues was that spamassassin didn't like it own database files
anymore after the system's OS had been upgraded by 4 releases.

Also during the last night the system crashed twice and required manual
intervention to reboot resulting in some downtime.  The cause of this has
been plugged as well.
