Live Mail separates the mail into separate folders.

Outlook puts all mail into one Inbox, you'd have to set up rules to separate it.

Both do IMAP, and spell check when sending, I believe you have to turn it on in both in Tools/Options, it's off by default I think.

Don't know about holding IMAP passwords for sure but they both remember POP3 passwords.

There's also Windows Mail which doesn't necessitate a Windows Live account like Live Mail, but it doesn't do separate folders, it's a slightly watered down Outlook.
