11212	Don't encode emails with base64/qp	phr	nobody	"#3472 introduced a patch, which replaces base64 encoding with quoted-printable.

Anyway, there's even better way to do get rid of unnecessary encoding:

{{{
from email import Charset 
Charset.add_charset('utf-8',Charset.SHORTEST,None,'utf-8')
}}}

The above will set Content-Transfer-Encoding to 7bit or 8bit as needed - exactly as Mutt or Thunderbird do
and completely solve the problem even for non-latin characters."	Cleanup/optimization	closed	Core (Mail)	dev	Normal	fixed	send_mail	petr.hroudny@…	Ready for checkin	1	0	0	0	0	0
