[issue25736] smtplib can't send 8bit encoded utf-8 message

Here is a workaround:

server.sendmail(mailfrom, rcptto, msg.encode("utf8"))

May be this would be better inside of smtplib?

[issue25736] smtplib can't send 8bit encoded utf-8 message

R. David Murray added the comment:

Although that will work for text-only messages if you know what RFC format 
looks like, you really don't want to do that in the general case, since you 
can't express messages that have binary non-text content using unicode.  What 
you want to do is prepare your message in correct RFC form, which is what the 
email library is for.  With the new API (provisional now, but any changes will 
be minor when it becomes final in 3.6), this is even easy (see the 
'contentmanager' docs).  Then you call smtplib.send_message, and the encoding 
to RFC format is taken care of for you.  In 3.5 it even supports SMTPUTF8, if 
you know any servers that do :)

Oh, and as for why this worked in python2: in python2 strings were binary, not 
unicode, so the non-ascii stuff was already in bytes form.

David,

many thanks for your information.

I think my e-mail format was correct - I've copied it from a maildir, as an 
"email file".

As I wrote, there is a solution: before the code passes the 'msg' argument to 
sendmail() function, it needs to encode() it as "utf-8", then it will be a 
bytestream, instead of unicode (which is the default type of any string in 
Py3). Meanwhile I realized it :).

Thanks again, and sorry for my mistake.

[issue25736] smtplib can't send 8bit encoded utf-8 message

[Ervin Hegedüs]

New submission from Ervin Hegedüs:

Looks like smtplib can send only messages, which contains only 7bit (ascii) 
characters. Here is the example:

# -*- coding: utf8 -*-

import time
import smtplib

mailfrom = "m...@mydomain.com"
rcptto = "m...@otherdomain.com"

msg = """%s
From: Me <%s>
To: %s
Subject: Plain text e-mail
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Disposition: inline
Content-Transfer-Encoding: 8bit

happy New Year

Ευτυχισμένο το Νέο Έτος

明けましておめでとうございます

с Новым годом
""" % (time.strftime('%a, %d %b %Y %H:%M:%S +0100', time.localtime()), 
mailfrom, rcptto)

server = smtplib.SMTP('localhost')
server.sendmail(mailfrom, rcptto, msg)
server.quit()


With Python2 (Python 2.7), this script finished succesfully. With Python3 
(Python 3.4), I've got this execption:

Traceback (most recent call last):
  File "8bittest.py", line 28, in 
server.sendmail(mailfrom, rcptto, msg)
  File "/usr/lib/python3.4/smtplib.py", line 765, in sendmail
msg = _fix_eols(msg).encode('ascii')
UnicodeEncodeError: 'ascii' codec can't encode characters in position 261-271: 
ordinal not in range(128)


Basicly, I don't understand, why smtplib allows only ascii encoded messages in 
Python 3. That worked (and works) in Python 2, and I think, that's the correct 
behavior.
