Because those are the 2 I'm aware of. I've been assured tha mailagent
should be invoked by a .forward file and will therefore need another MDA.
All the other mailers in debian use an internal MDA and can't be broken by
removal or procmail, etc.
My primary concern here is that spawning an extra shell process for each
mail delivery increases mail delivery overhead dramatically. I'd prefer
sendmail's current knowledge of what it is delivering to, so it can
support its features directly. Thinking about it, I believe deliver and
procmail need slightly different feature listings for sendmail, which
would make a generic script even more sub-optimal.
