RE: [Exim] cannot mail to external domains

I did but it did not seem to make a difference... I tired the network ip/24, localhost, and 127.0.0.1. I am looking up the
relay_allow option...
This maybe a stupid question, but I am used to restarting sendmail after I make changes, do I need to do something once I
make changes in the config file for exim besides save them?

Thanks,
