Comment:

 PHPMailer *should* detect the presence of an existing MIME-Type header and
 not add a new one.  If you were/are using an old version of wp_mail()
 however, which also set an explicit MIME-Type header (pre
 http://core.trac.wordpress.org/changeset/5764), you end up with duplicate
 headers before ever getting to PHPMailer.  PHPMailer does not remove
 headers, so you end up with dupe headers in your email.  I don't really
 see any good reason to set explicit MIME-Type headers in the calling
 function, and I think they should be removed.  Patch attached.
