Our all-in-one printer has a feature to scan documents and send them as attachments through the email. The printer asks for SMTP server IP and Port in its setting menu. It then tests the server to make sure it can properly communicate with it. The test went successful.
At the time of scanning, the printer asks for the recipient email address. I entered my local SME server as fargo@localsrv.local, but the printer failed to send to it!
I reference the email logs and did not find any error message. I also disabled SMTP authentication, but still get the same result!
The printer does not ask for a sender account and I think SME does not like such anonymous sender. Any thought please?
