Then something is wrong. Maybe you want "relay_from_hosts" set instead
(provided your ACLs support it).

That's good, for the internet atleast.

I wasn't sure, I had followed the thread some what.

Yes, I can understand how the "boss" feels about down servers. But while
it's an open relay, it's either be up and relay spam then get listed in RBLs
until you fix the problem and try to get off the RBLs, or be down and fix
the problem.

I like exim as well as it being the debian default. Very flexible. It's
like unix itself, gives you enough rope to hang yourself and the loaded gun
to shoot yourself in the foot. =)

Anyway, I still do not grasp exactly what you're trying to accomplish. Who
do you need to relay for? Are they outside your lan as well as inside? Do
you host other domains? Are you a backup mx for other domains?

If you can post your exim.conf file (w/o comments), I or someone else might
beable to figure out the problem.

you can run exim -bV (or exim4 -bV) to find out the config file location.
Send the contents of: grep "^[^#]" /path/to/exim.conf
That will strip most comments and blank lines.
