Python – wysyłanie maili w unicode

Chciałem wysłać z Python’a maila z krzakami tab by ładnie się wyświetlały i okazało się to całkiem nietrywialne.

Na szczęście googiel podpowiedział mi doskonałego gotowca, którego zamierzam zapisać by mi nie zginął:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import smtplib
from email.mime.text import MIMEText
from email.Header import Header
from email.Utils import parseaddr, formataddr

def send_email(sender, recipient, subject, body):
 """Send an email.

 All arguments should be Unicode strings (plain ASCII works as well).

 Only the real name part of sender and recipient addresses may contain
 non-ASCII characters.

 The email will be properly MIME encoded and delivered though SMTP
 to localhost port 25. This is easy to change if you want something
 The charset of the email will be the first one out of US-ASCII,
 ISO-8859-1 and UTF-8 that can represent all the characters occurring
 in the email.

 # Header class is smart enough to try US-ASCII, then the charset we
 # provide, then fall back to UTF-8.
 header_charset = 'ISO-8859-2'

 # We must choose the body charset manually
 for body_charset in 'US-ASCII', 'UTF-8', 'ISO-8859-2':
   except UnicodeError:

 # Split real name (which is optional) and email address parts
 sender_name, sender_addr = parseaddr(sender)
 recipient_name, recipient_addr = parseaddr(recipient)

 # We must always pass Unicode strings to Header, otherwise it will
 # use RFC 2047 encoding even on plain ASCII strings.
 sender_name = str(Header(unicode(sender_name), header_charset))
 recipient_name = str(Header(unicode(recipient_name), header_charset))

 # Make sure email addresses do not contain non-ASCII characters
 sender_addr = sender_addr.encode('ascii')
 recipient_addr = recipient_addr.encode('ascii')

 # Create the message ('plain' stands for Content-Type: text/plain)
 msg = MIMEText(body.encode(body_charset), 'plain', body_charset)
 msg['From'] = formataddr((sender_name, sender_addr))
 msg['To'] = formataddr((recipient_name, recipient_addr))
 msg['Subject'] = Header(unicode(subject), header_charset)

 # Send the message via SMTP to localhost:25
 smtp = smtplib.SMTP("localhost")
 smtp.sendmail(sender, recipient, msg.as_string())
