Hi all, i have an organisation that manages 3 domains from the one site, the 2 other sites are not connected via a LAN or WLAN, but for mail we manage their domains, i have a user that was created a year ago with our specific domain email address plus the 2 extra that we have setup in system manager. The problem that i am facing is that i can send to one of the email addressess but i cannot send to the extra domain email adressess thaqt this user has. Like i said earlier this has been working for over a year. No settings have been changed in MX records or domain, why would i be able to send to only one of the addresses and not the other. Any info would be greatly appreciated. Sorry i have an exchange server 2003 with SP1 on a windows server with SP1 as well.
