I have an application that logs its attempts to send emails. I got a the following message: Voter ID: 103XXXXX; System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.1 Unable to relay at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at VRSystems.clsSendEmail.SendOneEmail(VREmail myEmail, Int32 EmailId, String& ErrorMessage) Want to see if this error came from the mail server itself.

If you've enabled verbose logging on the receive connector, you can see the message where Rich mentions above. It sounds like you need to create a dedicated relay connector for Exchange or have your application authenticate to Exchange. Mike Crowley | MVP My Blog -- Planet Technologies

I'm pretty sure it did. If it hadn't the messge would have been accepted and the sender would have received a NDR. Ensure that "Verbose" logging is enabled on the Receive Connector(s) and you'll see the SMTP conversation in this directory: C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
