...which != "out of their house"; for example, my mailserver is in my
condo, but addressed out of a statically assigned /28 - which is
SWIPped and has rDNS delegated to me.

So far this hasn't proven to be a problem.  Averaging over the last 30
days, I have used 3158.7 bytes/sec incoming, 2235.1 bytes/sec outgoing
(both figures in error by less than 1 unit in the last place shown,
assuming netstat is telling the truth about byte counts).

Certainly my DSLAM could in principle be maxed out, but that seems
unlikely; more likely would be that my wire would be maxed out,
something that doesn't seem to happen in practice - at least not
unexpectedly.  (I have for example deliberately redlined it when
stress-testing it or the networks adjacent to it; I don't count that.)

Actually, for me, I believe it is the best way to run a mailserver.

That is, of course, taking into account issues such as cost.  Yes, if
cost were not an issue, I agree there would be ways in which it could
be run better.  But I daresay the same could be said of almost any
mailserver in existence.

Perhaps - but my experience over the past few years has been that I
have fewer problems inbound to my mailserver than through other
mailservers which forward to me.

Now, that could be just a question of what I view as "problems", and
where I see the problem as lying when I see a problem as present.  But
since it's my mailserver, it's my metric of goodness too.
