As far as I understand, Exim uses the NSS framework (libresolv (or whatever name it has))
to resolve userids, usernames, and such. So, if you manage to setup your
NSS in a way which provides the proper username for a numerical ID, Exim
should be happy.
You can use `getent passwd 2045` for checks. I believe, you can't
configure this NSS framework on a per-process base (except using
containers so such).
