The relay_domains is not so much an option but a data list, hence
exim is looking for something like,

relay_domains = "adomain.to.relay.co.uk:\
         anotherdomain.torelay.com:\
         lsearch;/opt/exim/etc/big-file-of-domains"


If you do want to relay for all domains then taking out all references to
'relay' in the config file should do that (I think..). As someone who
used to run zmailer 'open' like this it is a REALLY bad idea...

And exim kinda works it all out..

I think the thing here is that exim wants to be explicately told
what doins are local - where as you are hoping to get it to juts
belive the DNS.. dunno if you can do that - Phillip time ;-)

Hope I have understood you right and not just talked crap ;-) Not
sure about the UUCP stuff...

Cheers,
