[storing mail on the mailing list server, retrieval by POP3, instead of sending it out via SMTP as god intended]
You do realise that you're re-inventing Usenet?
hmm, I know it does sound similiar to newsgroups (aside from the protocol: NNTP vs POP3) but the key difference is that only people on the list can send mail (which I think is the default) against everyone allowed or moderation by one or more persons on newsgroups.
What I really think this idea is useful for is to use an existing mailing list software eg. Mailman, and to modify an exisiting option on it: (disable delivery :: on/off) to something like (Mail Delivery:: On/POP3/Off). So those who want can still get SMTP messages, those who don't want can disable mails totally. The killer app is when you are away for a time, and turn POP3 on for the duration. When you get back, just download the messages for the duration from POP3; this means your real mailbox is never full or don't receive soemthing like 200 messages which is quite possible ;-) And if you disable you cannot get them at all, and have to browse from the web or something. so best of both worlds :-)
I'd like to help for this idea, but as I suspect Mailman is in Python it'll take a bit of time to get used to it and I'll do it after my exams, something like after Jan 15. imho there is no point in writing something new, it may not be as well tested or known, just modify some already existing and working software (Mailman) to do what we need :-)
