Really useful. Just a quick note - I think using the getpass module instead of raw_input would be helpful for passwords.

I think you should create application passwords to avoid having to reduce the security of your account (available both on Hotmail and Gmail).

I can’t connect to the gmail server. What can I do to solve this?

I think there is an option to enable less secure applications on your google account.
