I sometimes think I'm one of the few people happily using Mozilla Thunderbird. It hardly ever seems to come up in these recommendations and when it does, it's usually accompanied by plenty of criticism about it not being updated regularly enough. But I'm happy using it for 5 email accounts and the ability to copy the entire profile folder to a new PC (or even use it directly from a USB stick if you're that way inclined) has been really handy for me in the past. The same profile folder can even be shared between 2 different OS's!
