Depending on the linux installed, you should be able to run 3.2 or 3.3 
instead of 2.7. Though there are still 2.x only modules, some things 
work better in 3.x (including default division).

3.2+ have a separate .send_message method for email message objects.

The 3.3 SMTP doc says that the fromaddr and toaddrs are only used by the 
transport layer and do not become part of the email message. The doc 
example has

msg = ("From: %s\r\nTo: %s\r\n\r\n"
        % (fromaddr, ", ".join(toaddrs)))

The body is appended after the double return. A subject line and any 
other standard headers would go before.

OT note: the PSF (Python Software Foundation) has bought a Raspberry PI 
and another ARM board to test Python on. I am happy to read that it 
seems to be working so far.
