We moved to a native 2007 enviornment last week. All works 100%. I am having an issue with sending BES Alerts from the BES Server itself. Tried to use local IP, fqdn, internal fqdn email, it can't find a valid SMTP Server. RIM support was clueless.
Funny thing is all my other devices/apps (APC, Antivirus, Monitoring, etc) send alerts fine through 2007.
Anyone have had similar issues and find a resolution?
