Just check the file permissions of the executable:

$ ls -l /usr/sbin/exim4
-rwsr-xr-x    1 root     root       669752 May 27 00:00 exim4
   ^            ^^^^
The marked elements mean it is "suid root" (set UID root), i.e. that
the process will run as root, even if the program is executed by a
non-root user.

The "euid=102" indicates it is _not_ running as root...
The easiest way to fix this is probably to reinstall exim4 properly,
in particular package exim4-daemon-(light|heavy), which contains
/usr/sbin/exim4 -- not sure what went wrong in your case.
