How do I reset Apple's Mail, in Lion, to default settings? I have been having a bunch of email problems and want to start over.  I have deleted all the IMAP accounts from Mail.  What other files do I need to delete, hidden and otherwise, to make Mail (and only Mail) just like a clean install?
The following directories should be empty:


~/Library/Mail
~/Library/Mail Downloads
~/Library/Application Support/Mail
~/Library/Caches/Mail
~/Library/Caches/com.apple.mail


The following files should be removed:


~/Library/Preferences/com.apple.mail.plist*
~/Library/Saved Application State/com.apple.mail.savedState
