Please don't drop an ontopic thread off the list. Added exim-users back
into the Cc list, also quoting more fully than normal.

OK, NAT router, 2 (or more) boxes behind it. Exim will be the target of
port forwarding through the NAT. You can do relay control based on the
originating address (relay by host - can't remember the syntax now)
since exim should see external port forwarded connections as having a
non-local address.

Basically you should never do relaying based on sender domain - its
trivial to get round. Do relay control based on host address and/or
authenticated SMTP.

Get exim4 first (some of the debian folks can tell you more on that than
I can), then use convert4r4 to transform your old exim 3 config file to
a first attempt at a exim 4 config. It will need some tweaking.
