I use something like this for allowing passwordless logins via gdm on my
desktop at home, where it's just me and my girlfriend:
auth    sufficient \
        file=/etc/gdmusers sense=allow onerr=fail item=user

And gdmusers is just a list of names. I am sure that pam_listfile or
something much like it could do what you want. Similarly, you can make
exim itself search a file, although that doesn't help your users
_retrieve_ said mail once it's accepted - perhaps courier or other users
can jump in and help out at this point.
