I'm a Gmail user, with 5 seperate accounts. I've always had problems with mail and thunderbird (freezing because of too many message to download, lack of gmail's threading support, etc). Mailplane is an interesting solution, but the way that it manages multiple accounts is really annoying. I would really like to figure out a solid Mail solution, as I have been using GMail Manager for Firefox for some time now, but have now switched to Chrome. Any ideas? What do you guys use, and how do you have everything setup? Thanks!
