That looks like it's trying to tell you to enable recipient filtering
and to not accept e-mail sent to addresses that aren't in the AD.
Doesn't that Barracuda have a configuration option to check the RCPT
TO addresses against the Active Directory? It looks to me as if it
does:

Have a look through the manual for the Barracuda, or call their
support folks. There's no sense in making Exchange do the lookup if
the security device is capable of doing it.
