Set up the SMTP domains in the Default Recipient Policy screen in System Manager.





Then set the appropriate SMTP address for each user in Active Directory Users and Computers. Make sure that you uncheck the option to Automatically update e-mail addressed based on recipient policy for each user.





You can set up branch to branch VPN tunnels with a Cisco PIX firewall. If cost is an issue, have a look at IPCop, an open source firewall %26amp; VPN package that you install on a spare computer with 2 network cards. http://www.ipcop.org





If you need "road warrior" VPN support, go with the Cisco PIX. IPCop's road warrior support sucks at present though that should be fixed in the next year or so. That said, if road warriors only need to connect to the main branch, you can use a PIX there and set up IPCop at the branch locations as it will do VPNs to Cisco PIX firewalls; it's a minor pig to set up but once you have it running you can forget about it.





If the only connectivity that users need from the remote offices is for e-mail, have a look at Outlook Web Access. There are some limitations but it's compatible with 99.99% of all e-mail messages.
