You won't be able to send mail using the smtp settings on these accounts from within ZCS, so you'll need to setup your server to be able to do outbound mail. You can setup how email will look (customize your name, and email address that appears when you send mail from that Persona), but you can't tell ZCS what server to send the mail out through. That is a feature of Zimbra Desktop, if you'd rather use that instead.
