There was a missing field on the submit method, so I've re-added so now the value it's been stored.

Following this topic, we needed to add a CA certificate to the SMTP configuration.
We added 2 options to be able to set up your custom CA certificate file, for this, we've created 2 extra fields.
1- Self-signed certificate, it's a boolean to determine if you need a custom certificate or not.
2- Certificate File, it's the certificate file itself.
