I'm moving from Yahoo! Mail after being with them for 10+ years. I have their plus service, so I can use POP/IMAP to move my messages (and my current ones are being forwarded now). My problem is that I have a LOT of email I want to move, and I know I can download it all to Outlook (which I pretty much have) and just move it over that way, but I have a bunch of filters that filter my mail.
Is there some automated service that will forward my mail so the original senders are preserved and then the filters could just move everything automatically?
