I mean those "install this package/use this script" solutions that
set everything up for you, configure, start services and so on.

Perfect.

I didn't even remember qmail-local. From what I remember (obviously
wrong) local delivered was done by maildrop.

Actually, exim gives you fine grain control over the whole
process, which actually helps you to understand who it works behind
the scenes (and sometimes makes configuration a hair-pulling
experience).

I can't really say how the whole transport-routing process
works for qmail. I tried to understand how it worked once,
and gave up after about 20 minutes.

And I guess here I reach the limit of tolerance the other
members have shown me on this issue, so I'll start replying
off-list :)
