 * When sending e-mails using the Newsletter plug-in, I see that multiple “MIME-
   Version” headers are added.
 * I’m sending using PHP method – Send emails directly: no
 * When using other plug-ins on the same WordPress installation, I don’t see duplicate“
   MIME-Version” headers.

 * Try to set send email directly, probably a 3rd party plugin is adding a double
   header. let me know.

 * Yes, I discovered that when NO§T using the mailer directly but relying on WordPress
   the header is added twice 🙁
 * Anyway, now the problem is gone. 🙂
