Pam says that you have no such user 'howell at tourforyou.info'. Pam most
probably talks to /etc/passwd (and friends), which means that you either
need to login with a valid valid system username listed in /etc/passwd,
or you need to setup some other userdb/passdb that supports full email
addresses as usernames.
