Comment (by filosofo):

 The problem is that wp_mail assumes the content-type is text, and it ends
 up thinking the boundary is the text encoding, or it ignores the boundary
 altogether.

 My patch fixes wp_mail so that one can send attachments using custom
 headers.

 I've also attached a test email message.  Send it to yourself using
 sendmail, e.g.
 {{{sendmail [name]@[domain].com < test_email.txt}}}

 and it works.

 Try to send it using wp_mail, with the 2-4 lines as custom headers, and it
 currently fails.

 Apply my patch, then try sending it via wp_mail, and it works.
