TypeError: character mapping must return integer, None or unicode

Following traceback occurs when doing connection.login(u'foobar@domain.com', 'justdoit') to issue an ESMTP.

Python 2.6.4 (r264:75706, Mar 11 2010, 18:33:18)

SMTP (RFC 2821) doesn't support non-ASCII envelope addresses.  A better behavior here would be for connection.login to raise a ValueError or a TypeError whenever a non-str is passed in.

RFC 5336, though, adds the UTF8SMTP extension, which adds support for UTF-8 encoded unicode mailboxes.  If the server advertises the UTF8SMTP capability, then smtplib could encode unicode using UTF-8 and pass it on.

This is really a feature request (RFC 5336 support), not a bug.

Plone currently just passes unicode data around, maybe additional documentation note will do for avoiding such trobules.

Thanks for quick response.
