Hold on here. First - reply to the list. I am too kind, I reply back and
copy the list. Don't expect this behaviour.

- If lots of people want to send you mail from outside to users on your
  server, this is a normal setup and there is nothing difficult.
- If you need your users to send mail via your server to somewhere else
  (relaying) then of course you will need a solution like
   POP-before-SMTP. This is usually in a "roaming" situation where you
   have road warriors (employees that move around and connect to the
   Internet via dialup to other providers, etc).
- If you want to only accept email from specific domains, and forget all
  other mail, then you need sender_restrictions.
