you also need to pass through those strings to the javascript from the
php backend. in the php bits you'd have these :

// load in the language strings from plugindir/localization/
$this->add_texts('localization/', false);
// send the strings to the client

likely, you'll call add_texts in your init() function, and add_label
inside a function you are referencing with register_action or add_hook
inside the init() function. you can call it in init() if need be, you
might just need to wrap it inside a test to make sure the add_label
function exists:

$this->rc = rcube::get_instance();
if (method_exists($this->rc->output,'add_label')) {

then inside your javascript you can call
rcmail.get_label('pluginname.somelabel') to get the localized version of
that string. (you can see the labels stored in rcmail.labels)

doing it this way allows the php backend and js frontend scripts to both
have access to the localized strings.
