Parsing All Mail from Mailbox File in Python

Maybe I'm going about this the wrong way, but I want to parse a single "catch all" email inbox via Python. I see the email module and I can make it parse an individual email, but what I want to do is open (for example) /var/spool/mail/catchall and parse all of the individual messages inside it. Opening that file and running the parser over it treats the whole thing as one giant email. How would I break it into individual messages?

Alternatively: is this A Bad Idea, given I'm going to want to delete the messages when I'm done with them? I'm tying this route instead of POP/ IMAP only because the server support isn't 开发者_如何学编程available right now.

You'll want to use mailbox to actually go through the mailbox.
