Double optin is OFF for Subscribe By Mail or should be for widgets and shortcodes

Hi,
Double optin is OFF for Subscribe By Mail or should be for widgets and shortcodes. So, there should be a different message like "Thank You. Success" or something like that instead of "We sent you a confirmation email" cause we did not as double optin is ticked to OFF.

See here http://screencast.com/t/6FDaJm3w3

How can we adjust the message BOTH for the Subscribe By Email widgets and shortcodes to adjust this?
