Just a wild guess, here. I wonder if exim is doing some name searching
for some reason? I have this problem with machined running ppp as a
daemon. If I try to telnet or ssh into such a machine, it will dial out,
despite the fact that my nsswitch and resolv.conf tell the machine to
look at the hosts file for local names. Bottom line is that telnet and
ssh do name resolution that will cause a dial-out if such a service is
available. So I just wonder if exim is doing something similar.
