#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ## Is not being sent to external emails
Posted on 2012-08-21
I have removed a user from AD and their email address from Exchange 2007.
When an internal email is sent to this deleted account, the recipient receives:
"#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ## " as they should.
But, if someone using an external email account sends to the deleted email address, they do not receive any bouce back at all. I would like for everyone to receive a bounce back if the email address has been deleted from Exchange.
Is there a setting to turn this on or off?
Thank you for your help!
