I've configured the PHPMailer plugin to how I think must be correct. But I have no way of knowing if it actually works. I'm not magically getting e-mail from it, so either it's not sending anything or it doesn't work. I can't know which is it.
I need some way of sending a test e-mail through zenphoto's e-mail handling stuff, or some way of triggering an e-mail send with 100% certainty, so I can at least get some idea of how well I configured PHPMailer.
So in short: what do I do to test PHPMailer config?
