Subject: [PATCH] Use EightBit encoding instead of Base64 for text types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously attachments with text/* or message/rfc822 encoding were
base64 encoded for no good reason. Change them to use EightBit transfer
encoding.
