I wonder if someone can assist in solving a problem I am experiencing. Our organisation has 13 offices around the country with an MS SBS2008 box in each office. Each office has its own email domain name and public DNS has been configured to deliver to their respective server. All offices are connected via SDSL VPN's, each site has a different 192.168.X.X address and the routers have been configured so that each address can talk to one another. This all works fine, access to server share from any network by UNC or IP address is possible and RDP between servers works fine by IP address.
Outbound and Inbound email at each server works fine too except to each other. I half expected exchange to send the mail out to the internet and back in via the public DNS but instead I just get mail stacking up in the exchange queue. If I create a forward lookup zone in DNS and enter a record for one of the other servers, within a minute or so I see the mail queue empty bound for that domain name. I dont want to have to create 13 forward lookup zones on all 13 servers just so that they can email one another accross the VPN so was wondering whether the hosts file could take care of this if set on the server?
We do not have a smarthost for sending mail either, advice on this would be most welcome.
