Well, I know some folks on this list who use LDAP for mail routing,
something we're beginning to deploy as well. I think LDAP will
scale better than NIS.

If the traffic I've seen on this list for the past couple of years
is any indication, it would seem that not a whole lot of folks are
using NIS or NIS+ on their MTA. Admittedly that's not a very
accurate indicator.

In all honesty, if your naming switch can't handle this, then you'll
see other problems as well. This is one of the reasons why we went
to NIS+ a number of years ago for our Suns. NIS+ is no panacea, but
the nis_cachemgr at least has some capability to handle server
failure more gracefully than what I ever saw with YP (shows how long
ago I did NIS that I still to this day refer to it as YP).

One thing I'd like to see is that the nss_ldap for Linux to include
support for something like ldap_cachemgr that's being developed in
Solaris 8. At least *potentially* this might make using LDAP even
more reliable. Alas, I digress.
