i specified exo-open as the handler for mailto: links in firefox and it works fine with sth like mailto:foor-bar@host.com, but when i try to open foobar_@host.com, i get a message that this is not supported. but it's a valid email address, so i guess it should work.
Created attachment 842 Possible fix Looks like the underscore was missing from the regex. Please check the patch.
sorry, i couldn't test the patch sooner, but i just got home and with the patch foobar_@host.com works fine.
