DNS knows the difference between "DNS servers not reachable" and "name
doesn't exist".  Only the most retarded email software would treat a
temporary DNS error as a permanent delivery failure.  Any sender who
would run software that does that deserves what they get.

Hosting everything behind a DSL line is still a pretty silly idea but
not for that reason :)
