I have WAN with 17 sites in a star configuration. the head office houses the main Imail server , IMgate and NAV gateway. The H/O Lan is connected to the Internet Via a Leased line. I have a firewall inplace to protect my LAN from the internet. i also use One To One NAT which translates my external MX ipaddress to my internal IPaddress - the Internal Address is that of the IMgate. therefore (hopefully) only the IMgate is visible from the Internet. Most of our users connect to the Imail server located at the head office - but as one of our other remote sites has nearly as many users as our head office and most of the emails from that office were to staff in the same location i felt it was cheaper to install an Imal peer at that office than to upgrade the WAN Link. All incoming Email comes into the IMgate box then passed directly onto the NAV gateway then onto my main IMail box. at this point it then gets farmed out to the second peer if needed. the IMGate has VRFY disabled (although i have had a spate of people trying to VRFY )
