CRON - adding multiple emails on MAILTO

I read that you can add multiple emails using a ,

I added this through the shell, but when trying to do it in NodeWorx I get an error for invalid email. If you can in fact put multiple emails I think it would be cool to add that ability to NodeWorx

InterWorx is obviously only validating the cron mailto for a single e-mail address, but it shouldn’t be too big a deal to change this to suport comma seperated (assuming it really works, which I have no reason to doubt).
