Simple Python script as SMTP server for outgoing e-mails?

What you're looking for is not an SMTP server but a Mail Transfer Agent,
called an MTA.

Pretty much all distros ship with an MTA by default, even if the SMTP
server part of it isn't installed or running. And often the MTA is, for
compatibility reasons, /usr/sbin/sendmail.

I'm sure there are MTA's implemented in python. Now that you know what
they are called (not SMTP servers!) you can search for them.

Dennis is correct, though, that most ISPs do block outbound port 25
connections for security and spam reasons, and require you to use their
SMTP server, which precludes the use of the local MTA.
