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 ?
Julien
