netbsd ships with a working mailer out of the box. (be nice if it *wasn't*
sendmail, but until there is a working in-tree replacement that requires no
further configuration, ie, "just works", sendmail is all we have to choose
from.)

Note that the paths named in this initial mailer.conf are almost
certainly going to have to be changed -- sendmail.sendmail will
probably turn into libexec/sendmail/sendmail or some such.
