As I posted to another one of your duplicate threads:
I would recommend you post this code and question to stackoverflow.com -- a
very popular site regularly visited by many programming experts who like to
answer technical questions (me included, when I have free time). You may
want to just tag the question as python and email, since it's not really
germane to google-app-engine (if you tagged it with the latter anyway, your
question might be avoided by experts on python and email who are not also
expert on App Engine).
