Not too sure on what you mean by entry points? If this is mail coming
from external to internal, then there are a number of ways that this
could be done. Setting up front end servers in a DMZ with a cname entry
for the servers on the internet would allow fault tolerance. Have mail
server setup in the east and one in the west. The number of front end
servers would depend on the amount of mail you expect to receive.
I think ISA is another option to have in there also but we haven't used
this although plenty in this forum appear to have.

I was wondering if any national/multi-city organizations out there could
share a little info with me, or if you know of any "best practises"
resources out there point me in the right direction. I'm looking for
case-studies or best practices in setting up multiple email entry points
within an organization; the main justification being fault-tolerance.
I'm trying to justify multiple entry points from cities in the east to
cities in the west, as opposed to a simply 1 or 2 entry points in the
east. Emails would be received by servers distributed in data-centres
from east to west running identical email gateway software and
configurations (anti-spam/content filtering/anti-virus).
Does anyone have any resources or stories to share? Any help would be
greatly appreciated...
