is there a way to set up a message on the server so that it will bounce back a specific message if an account is no longer valid.
ie: if someone mails [email protected] and jdoe is no longer an employee, has had his account deleted, the person who sends the email will get something back saying that the account no longer exists, can this be personalized to say something like "the email address you tried to send to is no longer valid, please contact us at 123-456-7890" or something to that effect.
thanks
