Python smtplib slower than PHP mail()

I ported some PHP applications to Python.

To my surprise, performance dropped by ten times in the newsletter module (100k+ subscribers). I was expecting some overhead for using SMTP (I think PHP calls sendmail directly), but not that much.

How can I speedup Pythons mail delivery?

EDITED: For anyone digging this question, I solved this using celery with 8 workers to delivery e-mail in background, with this setup I can deliver about 200K messages per hour. Celery integrates very well wit django, and AMQP rocks.

PHP's mail() does indeed use sendmail. You can do the same thing in Python by invoking it via subprocess.
