Stuart, 

I wonder if it makes sense to try to fold this into the email package?  

On a related note, Pycon2005 is coming up soon and I will be attending. 
There are four days of sprints preceding the conference and last year,
Anthony, Thomas and I sprinted on the new feed parser.  While we didn't
finish that work during the sprint, I think that session was more
successful than my following Mailman3 sprint.  The fruits of the email
sprint are evident in the new FeedParser that's part of email 3.0.

Does anybody want to sprint on the email package again this year?  Some
things we could work on include:

- An RFC compliant email address parser

- Adding better header support

- Adding a persistency and/or external storage API, or developing a
relational model for storing email messages.

- Another round of API fixes, and/or sprinting on bugs.

- Switching the Python stdlib away from deprecated modules such as
rfc822.

Let's gather some thoughts here and if there's enough interest, I'll
sign up for a sprint at Pycon2005.

-Barry
