spamd is SO slow

downloading e-mail with evolution is REALLY slow.
It takes about two minutes over a fast line to download 150 e-mails.

It's not a dns problem. I added the mail server to /etc/hosts before checking
e-mail, and it's not any faster.

Hurrah! Disabling non-local checks, did make spamd eat less CPU - MUCH less CPU.
Which makes me wonder what on earth it was doing..
I have filed a separate bug 198767 about evolution seeming to pass each
individual mail to spamd before downloading the next.
There is something wrong with your network, it is not slow on a properly
