Hi I need to setup new mail system for our new division of 50 users. . Our requirement is the 50 users should have all the functionality of internal as well as internet mailing. There will be maximum of one ISDN dialup to internet. In my Head Office (HO) office I have firewall, DNS, Exchange server 5.5 (mycompany.com domain) .presently three sites are connected to that. The new Division should have different domain. If I install an exchange server on my new office and use periodic dialup to my HO server exchange server is that possible to work ?. Is it possible to configure to domains my existing server?. All mails should come to my HO exchange server, and after dialup it should sent all mails to Branch server server and receive the outgoing mails for relay. I am bothered since both are different domains. Is this really possible. If anyone can guide me on this it will be really thankful.
