You said you were running a daemon, and you were running with GID=0, but
it wouldn't run with another GID. Now, I'm confused as to whether you
have got it setuid root or not at present, but:

In order to start up a daemon you need to have root privilege. Port 25
is a privileged port. Therefore you need either

(a) to have exim setuid root so that anybody can start it

or

(b) be running as root when you start the daemon

If it doesn't have the privilege, I would expect it to complain on its 
log file. OTOH, if it doesn't have enough privilege to write to its log 
file ...  (You could try looking also as syslog.)
