Here we reject everything we can as soon and as inexpensively (in terms
of server resource) as we can. Only a fraction of spam messages get as
far as ClamAV or SpamAssassin.

Subject: [exim] exim meltdown

My server has mysteriously locked up a couple of times in the last few
days.

I looked at it today and saw that all 4 cores were running at 100%, fans
were howling, and exim was getting hammered by messages.

I use spamassassin, dspam, and exim. Somehow the mysql tables for dspam
got corrupted, and (apparently) exim was in an endless loop.

I shut down dspam, spamassassin, exim, and repaired the mysql tables,
and all is well....

Is there any way to throttle exim so that it quits refusing messages
when system resources get close to saturated?

(I know this is a dspam/spamassin problem, but I'd like to get exim
smart enough to stop receiving messages if it's too busy while I figure
this out.)
