ReadyNAS 314 - Email alerts via Office 365 smtp relay

Firmware:  6.4.2

I am having difficulty with sending email alerts from this ReadyNAS via Office 365 SMTP relay.  I confirmed on other devices on the same network that the Receive connector is setup properly and our network engineer confirmed the Cisco ASA isn't blocking traffic.  I mimick the settings I setup in Veeam(which work) but nothing. Email account provider is the MX record for this org's office 365 domain, user/password is the full email account of a valid (yet unlicensed) account (this works for Veeam). SMTP port 25, From is same email address. I have tried with or without TLS but it doesn't work. We suspect it is something with the type of authentication the ReadyNAS performs.  Any ideas?

  • Well, some more tweaking and I realized that I merely had to follow Microsoft's instructions.   The SMTP relay doesn't require credentials. So, even though it worked within Veeam, the ReadyNAS wouldn't allow this to work.  I pulled the username and password, leaving only the SMTP server, port and from address and it worked fine.

  • This works for me with 6.4.2

     

    Account: custom

    SMTP-Server: ..xyz..mail.protection.outlook.com

    Port: 25

    from: somethingthatexist@yourdomain.com

    TLS: Yes

     

    on your MX Record must be an SPF Record of the outside IP from the gateway of your NAS.

      Hi wrobbins,

       

      Welcome to the community!

       

      I can see that this setup is not common and the workaround that you did could help other community members who are using the same email provider and setup. Maybe you can share some screenshots?

       

       

      Kind regards,
