What I did for my network is to hack courier to insert the remote IP address
for the customer when they check their email into a mysql table and have
exim check for an ip address to allow relaying...A lot like POP before relay
as done with sendmail often.

So what's the best way of controlling relaying, my users can log on from
anywhere, so host_accept_relay is out....
