In deed, using system accounts for authentication is not the best idea.
(The /etc/shadow is group owned by "shadow" - on many systems, but
your's may differ. You should find a reference system and check there.
May by you can peek at /etc/gshadow.)
If you do not use the system passwords, you're free to do anything you
want, from plain text password files (containing clear text or crypted
passwords) to database or LDAP lookups...
A good starting point is the exim documentation (spec.txt), about
section 34.3 (The PLAIN authentication). There you might replace "dbm"
with "lsearch" if you want to use plain password files (name:password).
Sorry for not sending a cook book example, but the spec is full of such
examples and I understood that you're about to learn(!) about exim. :)
