To quote http://docs.python.org/lib/SMTP-objects.html :
"The SMTP[sic] does not modify the message headers in any way."
The Received: header is being added by your SMTP server. Goodness
knows how PHP avoids it -- direct use of sendmail maybe?

Because "The SMTP[sic] does not modify the message headers in
any way." Or, to look at it another way, there are obvious
advantages to having message ids created by the client app
rather than the library. (OTOH, the library author is more
likely to write better id-producing code than the average
client app author, but IMHO this is outweighed by the greater
utility of having the app do it and the consistency of not
having SMTP touch the headers.) If PHP mail adds a message id,
that would be consistent with it using sendmail rather than
talking directly to the SMTP server.
