It appears one can't request a new password using their email address instead of their username. Above the field it says "Username or e-mail address:" however only entering the username allows the user to request the password. Entering their email address returns an error saying "example@site.com" is not allowed to request a new password."

logicalpat commentedI disabled the "login using username or email address" feature and found out that the request new password page claims to accept a user name or password by default regardless of LoginToboggan. I found this thread and it appears this may be a bug with the Drupal core: http://drupal.org/node/379296#comment-1299866
