Django SMTP authentication best practices

Question

I have a Django website and a postfix service running in the same Ubuntu Server 10.04 box.

What type of authentication would you suggest me so that it'll be simple and secure?
If I want my messages to be DKIM/DomainKey signed and compliant with sender-id (so that they don't end up being marked as spam) what should I worry about?

Anybody?

are emails only going to be sent from your django app? – ashwoods May 11 '11 at 21:54 — ashwoods, May 11 '11 at 21:54
Yes, a Django app is going to send them – Sergio May 11 '11 at 22:05 — Sergio, May 11 '11 at 22:05

There's a very good explanation by Jeff Atwood about email authentication mechanisms.

Django itself doesn't support DKIM out of the box, but there is a useful snippet you could use to get started. It's a subclass of EmailBackend that automatically signs your message and includes the DKIM-Signature header.
