Local delivery is only an essential feature if you actually want it. I've
run enough machines which forwarded everything to a smarthost and never
actually delivered mail. I wasn't so short on disk space that I
complained that deliver forces you to have an MDA even if you don't want
it though, which may be a valid complaint in itself.

I'm still wary of the virtual-package/update-alternatives approach, but
can be convinced of it if necessary. My main concern is the fact that a
seperate script would be required as deliver and procmail take seperate
options. This may create a point of failure and unreliablity in delivery
by procmail in extreme cases. It definatly increases the load somewhat by
forcing a shell to be spawned.

Sendmail is (IIRC) the only MTA in Debian that requires a seperate MDA.
All the rest (qmail, smail, exim) have local delivery built in and only
require an MDA if it is stuck in their .forward (or equivilant) file.
