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..

Relay address exists OK emai@somedomain.com (Valid) Failure email.bad@somedomain.com (Invalid) 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: http://www.mailenable.com/kb/Content/Article.asp?ID=me020528 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. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
