[New-bugs-announce] [issue4403] regression from 2.6: smtplib.py requiring ascii for sending messages

[August Mueller]

New submission from August Mueller <gus at flyingmeat.com>:

smtplib requires that messages being sent be in ascii, and throws an exception otherwise.  
Python 2.6 doesn't require this.  Here's the diff where it was introduced:
http://svn.python.org/view/python/branches/py3k/Lib/smtplib.py?rev=59102&r1=58495&r2=59102

Is there a good reason for this?  I use python for a webstore, and send out emails for folks 
with multibyte names (for instance, if a name has an umlaut).

Here's a code snippit + exception:

Python 3.0rc3 (r30rc3:67312, Nov 22 2008, 18:45:57) 
[GCC 3.4.6 [FreeBSD] 20060305] on freebsd6
Type "help", "copyright", "credits" or "license" for more information.
>>> import smtplib
>>> server = smtplib.SMTP("localhost")
>>> server.sendmail("gus at flyingmeat.com", "gus at flyingmeat.com", "Ümlaut")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/mu.org/home/gus/unix/python3/lib/python3.0/smtplib.py", line 713, in sendmail
    (code,resp) = self.data(msg)
  File "/home/mu.org/home/gus/unix/python3/lib/python3.0/smtplib.py", line 481, in data
    self.send(q)
  File "/home/mu.org/home/gus/unix/python3/lib/python3.0/smtplib.py", line 305, in send
    s = s.encode("ascii")
UnicodeEncodeError: 'ascii' codec can't encode character '\xdc' in position 0: ordinal not in 
range(128)

Is there a workaround or a new way of using it?  I couldn't seem to find it.

Thanks!
