Notification connector error

Hello,

 

I am trying to use an email notification connector but without success. When
the connector tries to send an email I keep having the following error:

 

Email: Error sending email: Could not convert socket to TLS

javax.mail.MessagingException: Could not convert socket to TLS

The connector is configured with a gmail SMTP, using the configuration
recommended by the documentation:

 

Hostname: smtp.gmail.com

Port: 587

 

Configuration properties:

mail.smtp.ssl.trust : smtp.gmail.com

mail.smtp.starttls.enable : true

mail.smtp.auth : true

 

 

The username and password I use are correct and I also tried with the
office365 SMTP and I get the same error. 

 

I am using openjdk version "11.0.11" 2021-04-20. Do you have any idea about
my issue ?

This used to work fine, but I suspect that when SSH was declared unsafe, it
was disabled, and now only TLS will work.
