 `wp_mail` is kind of a beast. I noticed various plugins having to copy all
 250+ lines if they just want to change one small thing. It would be better
 to have smaller helper functions that do some of this logic. Plugging
 functions would have to duplicate less code which is
 [DRY](http://en.wikipedia.org/wiki/Don't_repeat_yourself).

 We could cut out 75 lines by abstracting `get_mail_headers()`, more lines
 with `get_mail_from_name()`, and yet more with `get_mail_recipients()`.

 It would be great to abstract some of this functionality so plugging
 functions have less they can mess up. And less to update in case the
 functionality every changes.

 If someone gives the go-ahead I'd love to submit the patch myself. :)
