Using Python's smtplib with Tor

Question

I'm conducting experiments regarding e-mail spam. One of these experiments require sending mail thru Tor. Since I'm using Python and smtplib for my experiments, I'm looking for a way to use the Tor proxy (or other method) to perform that mail sending. Ideas how this can be done?

Answer 1

1. Find the port tor is running on. It is an HTTP Proxy
2. Write code that connects to an HTTP Proxy (ie: non-SOCKS), ip address 127.0.0.1:[tor port]

Answer 2

Because of abuse by spammers, many Tor egress nodes decline to emit port 25 (SMTP) traffic, so you may have problems.
