RFC 2046, section 5.2.1: https://tools.ietf.org/html/rfc2046#section-5.2.1

   No encoding other than "7bit", "8bit", or "binary" is permitted for
   the body of a "message/rfc822" entity.

So the answer is in the RFC: You're not allowed to use base64 encoding
for a message/rfc822 attachment.

Dianne.
