The Jolla-Mail app sends also simple text mails base64 encoded:

Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: base64

Why not sending mails as "quoted-printable" like the N9 ?

Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

Do you have any use case for this ? Encoded emails will reduce data transfer a little bit.

I think you got it backwards: base64 encoding increases the size.
From Wikipedia:
Thus, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original data length, though for very short messages the overhead can be much higher due to the overhead of the headers.
