I do the same thing via RSS, using Google Reader, and it works much better than email. Unfortunately, most of the mailing lists I'm interested in don't have RSS-ified archives. So I wrote a short script that downloads email messages directly into an RSS feed; this is just a quick post to share it with the world: http://github.com/danshoutis/mail-to-rss
Here's the short rundown on how I've set things up:
- I set up a filter in gmail that automatically labels mailing list traffic and has it get archived immediately.
- The email-to-rss script downloads new messages from that gmail label, converts them to HTML, and builds an RSS index. I have it save the results into a public dropbox folder to save me the step of uploading them to a server somewhere.
- Then, I just give the public address of the final rss file to Google Reader, and schedule the script to run automatically.
