You can use the standard module, MimeWriter, or, IMO, the mimecntl
module <URL:http://starship.python.net/crew/arcege/modules/mimecntl.py>

For example with mimecntl, to include an image in an outgoing email:

>>> f = MIME_document('''\
Hi there, mom.  I just wanted to tell you that I enjoyed Christmas.  Thank
you for the mittens, they fit well.
''',
...   type='text/plain',
...   From='arcege@shore.net', To='my.mom@home.net'
... )
>>> print f.read()
>>> f['subject'] = 'Many thanks and holiday wishes'  # add a header
>>> f.write('Love,\n\tMichael')  # I forgot the signature
>>> from_addr = str(f['from'])   # who is sending it?
>>> majortype = f['content-type'].majortype()  # 'text'
>>> # send a picture
>>> imagefilename = 'card.gif'
>>> image = open(imagefilename).read()
>>> image = MIME_recoder(
...     image,
...     ( Field('content-type', 'image/gif', name=imagefilename),
...       Field('content-length', len(image)),
...       Field('content-disposition', 'attachment', filename=imagefilename),
...     )
...   )
>>> # now we encode it
>>> image.encode('base64')
>>> # make a new enclosing document instance
>>> # get f's headers to put into the new document
>>> f_fields = f.values()
>>> # we need to remove the content-type header field
>>> f_fields.remove('content-type')
>>> g = MIME_document( ( f, image ), fields=f_fields )
>>> 
>>> from smtplib import SMTP
>>> sender = SMTP('localhost')
>>> sender.sendmail(from_addr, (str(g['to']),), str(g))
>>> sender.quit()

The MimeWriter, in my mind is a bit more complicated to create the
same.
