--------------------------------+-----------------------------
 Since 5.2.10, PHPMailer has added a new feature to automatically use TLS
 encryption when available at the SMTP server side, via `SMTPAutoTLS`.
 This setting is `true` by default which is kind of security feature but in
 real life this is causing headaches due to wrongly configured SMTP server
 with regards to TLS support (see e.g.:
 https://github.com/PHPMailer/PHPMailer/issues/642,
 https://github.com/PHPMailer/PHPMailer/issues/643).

 That setting should be set to `false` to allow WP admin people to select
 TLS support **only when** it is actually supported by their SMTP server.
