Configuring secure email notification in Sonarqube

I have configured email notifications on sonarqube , but I am not able to establish a secure connection for emails . I was trying to use secure connection as ‘ssl’ and ‘starttls’ with port 465 and 587 respectively. But that didn’t work . Can I get some help on how I can establish secure mail connection?

Can I get some help on this one ? What should I enter in SMTP username , SMTP password fields when creating a SSL secure connection with port 465 .
Thanks in advance!!

Same issue :frowning:

The same SMTP config works with several tools but not with Sonar:


  • port 587, 465 and 25
  • with and without SSL and STARTTLS

Still the same issue:

535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6 . Sending the email to the following server failed :


  • SMTP_SERVER has been replaced
  • Sonarqube 7.7

Any idea?
