How to send E-mail without an external SMTP server ?

[fdu.xiaojf at gmail.com]

Hi,

I just want to send a very simple email from within python.

I think the standard module of smtpd in python can do this, but I 
haven't found documents about how to use it after googleing. Are there 
any examples of using smtpd ? I'm not an expert,so I need some examples 
to learn how to use it.

Or maybe there is a better way to to this?

Thanks.
