When visitors send comments through your site's Contact US page, the messages must be stored somewhere on your webhost's site, under your hosting account, or sent to an email account that is provided by either your host or another mail provider. If you add that account to TB as an IMAP account, applying the settings recommended by the mail provider, you should be able to access the messages as with any other account in TB.
