I use Mail for my Gmail and Hotmail accounts (Hotmail works courtesy of MacFreePops) and it's amazing. My problem rests with Hotmail though. This isn't another "HALP I CAN'T GET HOTMAIL TO WORK WIT MAIL" thread. This is a little different. Every now and then, my hotmail account starts to redownload my inbox...again. Essentially doubling my hotmail account and forcing me to rebuild my Hotmail mailbox. This generally wouldn't be a problem but I have about 3900 emails. It's very pesky rebuilding such a large inbox as it takes forever. If someone knows why it does this and how to make sure it won't be done again, please please inform me.
