call-forwards (which I hope is the case here) are great, as long
as they're cached (which exim does). We do all want to avoid
backscatter, I hope :)

I think the Rotating SMTP Outgoing IP addresses is a bad idea.
You should already be using parallel sessions, so the pipe is
nearly full, I'd hope. If you can shove additional items over
the same session, that helps too (though I don't know exim's
specifics in this area). You want to rotate IPs, send from
multiple physical hosts.

Trying to make smtp into IM is silly, imho.
