It MAY. It doesn't always have to be so (at least thru 4.6X). Mine are neither.

.. or when and where the exim binary is NOT setuid root, delivery was not
invoked by root, and the particular delivery transport doesn't need either
because it calls for delivery under an EGID of which the exim daemon runner is
a *member*...

Or .. just maybe applicable here .. as above, but the running UID/EUID is NOT a
member of the egid the tranport calls for to make this delivery (gid 104)?

The Devil is in such details...
