Unable to send emails or reply to emails. Ive run the Exchange troubelshooter tool and it comes back saying "smtp instance fully-qualified domain name does not match DNS resolved server name". One of the steps to fix is to enter the FQDN into the advance properties of the mailstore. The name in there at the moment is <domainname.com>. Im still a bit of a newb when it comes to this stuff but is the correct FQDN or how do I find this?
All help appreciated
