[thelist] Exim mail relay issue

[Russ]

All...

I've got exim set up on a box running Fedora, and for some reason, it
isn't relaying mail from localhost to recipients not on the same
server--when running ColdFusion pages that are pushing out emails (just
so you know that CFMX is running as well) or any other time.  

If while on the server I do a "telnet localhost 25" and send mail, it
works, but if I do a "telnet [hostname] 25" and do it, it fails, even
though it should be recognized as a local host.

Seems as if this should be rather simple, but I'm spinning my wheels all
over the place.  Anyone experience this before?

Thanks,

Russ
