I have a Barracuda spam filter in front of my Exchange server. It it telling me that the mail server is accepting invalid email addresses. How do I stop this? Your mail server is accepting invalid email. To improve the performance and accuracy of the Barracuda Spam & Virus Firewall, please configure your mail server to not accept email to invalid recipients and/or domains. You may also want to verify your LDAP server configuration. Relay address exists OK emai@somedomain.com (Valid) Failure email.bad@somedomain.com (Invalid)

Seems you are using suffix like @domainname.local and the mail for which your Barracuda is giving error doesn't have this suffix. If you don't need @domain.local then remove it from Email policy and then remove from accepted domain. thanks Amit Rawat

Sorry - I dont quite understand. I am a REAL newbe and need to be spoon fed..
