Sign... My Guinevere 3 box which has been humming along all these years
just started processing about 10 messages a minute. Neither reboot nor
cleanup nor turning off bayes has made it happy. I look at the mail
piling up and I wonder how I spurned her so. Apparently 3Ghz and 2GB of
ram isn't making her happy anymore.

Seriously however there's something very very wrong. I'm rebuilding it
on another box temporarily to see if that runs better.
