SMTP authentication method


Recommended Posts

Posted

Hello,

 

Requesting AUTH PLAIN in unraid please.

 

I'm trying to configure SMTP settings for email notifications and running into an issue with authentication.

The unraid log shows below error

5.7.8 Error: authentication failed: Invalid authentication mechanism

Email provider says this error means the system used an outdated or unsupported authentication mechanism (such as AUTH LOGIN) to send the test email. They require using the AUTH PLAIN mechanism to send emails.

 

Thanks!
