 A support ticket I came across raised some issues with the header encoding
 (“RFC-violating Content-Transfer-Encoding header”). User states that our
 header ends with:

 {{{
 <br/>
 Content-Type: multipart/alternative;
 boundary="b1_d6f7a7912dabccf69ce9130965f76239"
 Content-Transfer-Encoding: quoted-printable<br/>
 }}}

 And quotes:

 "The RFCs state that the only allowable C-T-Es for multipart/alternative
 are 7bit, 8bit, and binary; Q-P is invalid. This causes my MUA to refuse
 to display the email. See http://tools.ietf.org/html/rfc2045#section-6.4"
