What is the easiest way to send e-mails using Python?
Can you show me a sample not complicated script?
Regards

Ali,

I wrote something not long ago that might help.  The script itself isn't
TOO complicated, and calling it from other modules was designed to be as
simple as I could think of making it.  It supports attachments too,
which is pretty keen (if I do say so myself)

It's also available at
