According to:


the second argument to 's.sendmail()' needs to be a list, even if it is a
list of a single element.  I'm not positive that this is the bug, but it's
a possible error.  The code also mentions that it's talking to your local
SMTP mail server.  Is that right?

Otherwise, I'm not quite sure yet.  Try turning on smtplib's debug mode by


and try again: it should spit out more debugging information to help us
see what's going on.

Good luck!
