My reasoning is that very few of the special uids (bin, daemon, etc.)
should ever recieve any mail; and it doesn't take much security paranoia
to want to prevent deliveries under those uids. Since tradition says
that those accounts (except for 'nobody') occupy a range of low numbered
uids; with 'real' users starting at some arbitrary round number (100,
500, 1000, etc.) it would be convienient to restrict the entire range
rather than have to remember to update your exim config when adding or
removing one of those accounts.

Hmmm. I missed that thread. I just did a search on the mailinglist
archive - lots of hits on 'never_users'; but nothing that looked
relevant. I'm willing to be convinced though. Could you point me
at (or briefly summarize) the rationale and arguments on both sides?

And you do a damn fine job of it too; if I may say so. But I had
to leave open the possibility that I had just missed something
that was in one of the sections discussing more generic aspects
of option syntax.
