yes, in the common case, initgroups(3) is run.

if you launch it as the exim user rather than as root (e.g. in inetd
mode, or when listening to a high port so root isn't needed),
initgroups(3) isn't run, since it is assumed that the environment is set
up correctly already. at least that's my reading of the code.
