Formmail from Tectite - Setting target email address

[tdrsam]

I'm using a plugin that sends messages from forms to an email address. It's from Tectite and their website is here.
I'm having trouble setting the target email address. This is the target email line in the formmail.php file:

$TARGET_EMAIL = array("^unrestinpeace@yahoo\.com\.au$");

And this is the hidden field in the form:

<input type="hidden" name="recipients" value="unrestinpeace@yahoo.com.au">

I can't figure out what I've missed.
