In fact, if you are looking at qmail-users, you might as well forget
about the NIS completely, and just use one single user id/group id for
the mail server setup. The assign and the cdb duo are far more
scalable than NIS. I don't think NIS is good for any site whose user
number may keep growing. NIS craps out around 30K users or so, owing
to a ndbm 1K buffer limitation. I
have been told by Sun's Enterprise Services (we have support contact)
that this "bug" is not going to be fixed :(

Agreed.
