Comment (by jrf):

 @zodiac1978 Please check what has been backported already. In the case of
 older WP versions, the version of PHPMailer shipped with it will generally
 not be updated anymore, but individually security patches will be (and
 have been) backported.

 So, while the version number of the PHPMailer package shipped with those
 older WP versions may give the impression it is not a secure version, the
 ''actual'' code shipped is often the official version + backported
 security patches.
