[Email-SIG] smtplib and getting a copy ?

Dear Lukasz,

> Is message id generated by sending server or receiving server?

It's intended to be created by the program that sends the mail, but
it's technically optional. The details are at:

http://www.faqs.org/rfcs/rfc2822.html

If the sending program doesn't create a Message-ID header, one will
likely be added by some intermediate server.

Python's email module has a convenience function to create one that
should be sufficient. It's documented at:

http://docs.python.org/lib/module-email.Utils.html

For example:

>>> import email.Utils
>>> email.Utils.make_msgid()
'<20060413221549.2140.4129 at mint-julep.mondoinfo.com>'
