For anyone who is interested, I've written up a document on
how to install OpenBSD, configure it as a transparent bridge,
then install spamd on it. It was written primarily for our
campus computer center who want to know how to do it if something

Yup! Thanks. Linux uses ALT-Fkey which I tried. Didn't try
adding CTRL. :-/ Assumed it didn't have it, and too busy getting
everything else working to go look for

James is right, it's a design flaw of spamd that two failed attempts
are required. This is what happens:
I wanted to set up a system which has two ether cards (it's part of
a transparent bridge so it'll be inline with someone's connection)
such that it'll pick up a DHCP address on *both* cards ... the trick
comes from not knowing in advance whether the DHCP server will be
on the inside connection or t

You would think so, but you would be wrong. As I was when I started

I hope this isn't too OT for this list, but..
If it's that popular it's worth setting up a torrent!

Although I know where David is coming from with this slightly
contentious comment, he's wrong. The argument is that most
senders will do their own back-off, and the hassle of setting
up a *good* backup MX server is so high that the benefit scarcely
justifies it.
However where he is wrong is not i
