Message:

Update PHPMailer to 5.2.7 from 5.2.4.

Includes two trivial modifications for WordPress:

• Doesn't use the autoloader, so the check to enforce the autoloader from the constructor is removed.
• Requires class-smtp.php for backwards compatibility with direct (non-wp_mail()) uses of PHPMailer, as the autoloader isn't used.

props bpetty.
fixes #25560.
