You need to be an "admin user" in the Exim sense. The easiest way to do
this is to add yourself to the exim group, assuming you have defined a
group for Exim to use.
All of the exim spool directories/files are owner:mail group:mail. This
makes me think 'mail' was compiled in as the exim user and group.
If I login as mail or root from xdm then I can run eximon no problem.
If I su to mail or root then I get X authorization problems and can't even
get eximon up.
I noticed that files in the queue have no group privileges so adding myself
to the mail group does not let me manipulate or even see queued mail unless
I go and chmod all the files in the queue.
How do other people run eximon? Do you really have to login to xdm as the
exim admin?
