SMC is unable to relay

jkalten

Hello everybody here at this board!

I'm new here and with the Sophos Mobile Control. Our SMC should be configured to use it with iPhones. With an activated SIM-card there are no problems, but the hugh amount of the phones must be configured witch inactivated SIM-cards over the push function by SMTP. And here is the problem, that the SMC say in log-files 

SMTPAddressFailedException: 550 5.7.1 Unable to relay

But I don't where the problem is. A mail account on the phones is set up and receive normal mails. In the Sophos Configuration Wizards is the test mail send correctly - so the connection to the exchange server is established. But when I go to the device inventory and press the icon to deploy mobile phone or send an order packet it came to error -7 for this order and in the log is the error from above.

Thank you for your help

Best regards,
Jan

    Hi Jan,

    sorry, for the late response.
    I did a short test in my test environment and was able to reproduce the error by disabling the "Anonymous users" in the "Permissions Group" tab of my default Exchange Receive Connector.

    You mentioned that the test email was sent correctly before. Were there any changes performed after the initial setup of SMC? How was the SMTP setting configured before within SMC?

    The root cause is obviously somewhere between your Exchange and the SMC server. Maybe you can check the settings of the exchange again? Is it possible, that the SMC server is not allowed anymore to connect to the Exchange server?

    What do you enter exactly as Originator address in the SMC setup? You should use an address belonging to your company, e.g. smc@company.com which exists on the mail server.

    Best regards
