Mailbucket is an experiment in alternative methods of email management. For now its only feature is a public email-to-RSS gateway: forward your email to
slurp@mailbucket.org and have your news reader pick it up at mailbucket.org/
slurp.xml (where you choose
slurp, having checked that it's not already in use).
The service is probably most useful to those who
lurk on high-traffic mailing lists, but it could also be used as a rudimentary bridge between applications, with email as the transfer protocol.
The generated RSS feeds are valid and compressed (if your client supports compressed content); they are also public and impermanent, which may be a disadvantage for you.
