In transition to a new mail server (with a new address), I installed a
plug-gateway on the old server to redirect mail.

Unfortunately, plugd hides the ip address of the sender, and since I trust
my netblocks, all of the ip addresses on the old server became "spam relay
entry points".

It took the spammers 96 hours to find 3 of the addresses on that box and
for us to be listed in orbs.  I figured I would have at least had a week
or two to figure out a better way.

I ended up staying up all night getting transparent proxying to work right
on the new server and making it work with a cisco route-map.
