SEN015 warning when configuring the SMTP server

SEN015 warning when configuring the SMTP server

Symptom

The following warning appears: SEN015 The request was aborted: Could not create SSL/TLS secure channel.

When an email is sent by the application:
  1. SMTP Configuration Test in the Administration Console.
  2. Email notifications in a task, watcher, or any other email-sending action of 360Suite.

Reproducing the issue

  1. Go to 360Suite's Administration Console.

  2. Go to Technical.

  3. Fill the SMTP configuration with your SMTP server information without selection an SSL option.

  4. Fill your username and password.

  5. Try to send a test email to verify your configuration.

  6. A warning appears : SEN015

Cause

The connexion to a Microsoft SMTP server (like Exchange) with credentials on a non-secured channel (SSL/TLS disabled) is not supported by the JavaMail library used by the application to send emails.

Resolution

Switch to a secured communication channel by enabling the SSL/TLS option in the SMTP configuration of the application, and change the SMTP port used accordingly.


Please note that your SMTP server must support SSL/TLS encryption.

Solution 2

Remove the credentials from your SMTP configuration, to avoid passing credentials over the network on a non-secured channel. This is only possible if your SMTP server accepts connections without credentials.
