[exim] accept multiple domains

Hi List

I know this is a newbie question, but i have to start somewhere! ;-)

I have set up exim v4.69-9 to recive mail for my domain "lfweb.dk" and
it works fine and delivers mail in maildir. I have looked in the spec's
but i cannot get it to recieve mails for my domain "gma.nu". It rejects
emails for all but the lfweb.dk domain.

I use a split configuration file(s).

Can you give me a hint about where to start?

Thanks.
Best regards
Lars Nielsen
