You obviously don't run a site where many of your users foward-through
your site. I've seen a large site with many forwarding users get
blocked by spamcop because of how their system forwards messages without
preserving the Recieved: lines... spamcop lists them often enough these
days to be more than annoying.

It's also a good reason never to strip off Recieved: lines. :)
Or, its a good reason to make sure that the outgoing mail server is a
different ip and block than any names that are shown in Recieved: lines
for incoming mail.

Off the top of my head, I would recommend dsbl over spamcop.

But hey, its your users, its your server.
