actually, no. he meant chmod +s /path/to/exim/binary/exim

exim starts as root (so it can bind itself to the interfaces n stuff),
then drops privileges and truns as EXIM_UID. whenever it needs to be
root again (eg for doing a local delivery) it reexecs itself so it
turns root again (thats because of the setuid bit). so what you
actually (likely) to need is the exim binary be setuid root (and owned
by root:root !), and EXIM_(U|G)ID be 'mail' or whatever.
