Every once in a while, my ISP's SMTP server refuses to send perfectly legit e-mails because it considers them as SPAM.
So I'd like to install a dead-simple SMTP server on my XP computer just to act as SMTP backup server. All I'd need is to change the SMTP address in my e-mail client, and off they go. No need for anything else like user authentication or SPAM control.
Is there a no-brainer, ready-to-use solution in Python that I could use for this?
