Summary: mimetools message's To field can't be changed

Initial Comment:
Steps to reproduce:

>>> from email.MIMEText import MIMEText
>>> msg = MIMEText('')
>>> msg['To'] = 'foo at bar.com'
>>> msg['To']
'foo at bar.com'
>>> msg['To'] = 'foo at baz.com'
>>> msg['To']
'foo at bar.com' (should be @baz.com?)

Same problem exists in Python 2.4.3 and Python 2.5b1.

Remember that you can add multiple headers to any message,
so in you're example you've added two To headers.  Also
remember that the dictionary interface will return one of
those multiple headers, but not all of them.  Use
msg.get_all('to') to see them all or del msg['to'] to delete
them all.
