From experience: Don't emerge exim. Download the tarball and do it
yourself. But this thing is actually a GOOD thing. You DON'T want to
process ANY mail as root! BIG SECURITY HOLE! What should happen is that
you are delivering mail to users as that user. Something to check in
your exim.conf that may help:

in your local_user router, or your local_delivery transport. Do you have
a user specified? i.e.
user = <value>

if so, is it a fixed user, like
user = mail

or is it a variable, i.e.
user = $local_part

the best setting is the last one. Then Exim changes to the user,
delivers the mail, and changes back to the exim user (as defined in the
Makefile).
