I edited the exim.conf file and took out the restriction on relays from any local domain to a non-local one... so my Debian box werks now but... the RedHat6.2 one has /etc/mail/access as you suggested at first. This already contains lines to allow relays from localhost etc. but it still doesn't werk. Do you know where any other restrictions are on how to unrestrict outbound mail traffic? I'm very thankful. TTFN.
