I guess the convention is quite old and it was probably deemed more
reliable to have messages pushed to a known "Always on" machine which
could perform retries etc if for some reason the eventual destination
server was having a bad day? In any case this was more than likely a
dedicated machine on the local network within the business, and probably
quicker in the early days.
2. seems to work fine for me, I guess volume might be a factor but with
modern machines as fast as they are you probably won't have to worry
about that.
I have not done anything like this with MS software, I have used Debian
Linux and webmin to administer things, so can;t help with specifics.
