The best would be if you can find another secondary MX quickly.

Our server is doing better now, so I hope this problem is intermittent
and will go away, as it has done the few times this has happened before.
The mail queue is already down by half.

If you can't find anyone else, I could set up one of our secondary MX's
to be secondary MX for xemacs.org instead.  They are much less loaded,
and much less important systems, and they run modern Debian
installations which are easier to debug and fix.  On the other hand,
they have a 50GB per month limit, but I don't think we'll run into it.

If you want to make the switch, let me know and I can set up
mejsel.josefsson.org as the secondary instead.
