Symptoms

When setting up your email server for use in Protect via Tools > Operations > Email, you see the following error message:

The remote certificate is invalid according to the validation procedure.

Cause

You are attempting to use a secure connection with your mail server, but a certificate or TLS connection is incorrectly configured for the mail server.

Resolution

• Verify that any certificate required for the mail server is configured correctly and that TLS connection is available for the mail server.
• Ensure that the port is set correctly.
• Ensure that credentials provided are valid with the mail server.

A possible workaround is to set up using a mail server which does not require a secure connection.
