Answer 1

Usted sólo debe añadir 'utf-8' argumento para sus MIMEText llamadas (se supone 'us-ascii' por defecto).

Por ejemplo:

números de línea

# -*- encoding: utf-8 -*- 

from email.mime.multipart import MIMEMultipart 
from email.mime.text import MIMEText 

msg = MIMEMultipart("alternative") 
msg["Subject"] = u'テストメール' 
part1 = MIMEText(u'\u3053\u3093\u306b\u3061\u306f\u3001\u4e16\u754c\uff01\n', 
       "plain", "utf-8") 
msg.attach(part1) 

print msg.as_string().encode('ascii')
