I just saw this server error. Confirmation email not sent. Any idea what this means and what steps I can take to prevent this?

This is just saying that when PHP tried to hand off to the mail program, it failed. Unfortunately, we don't have any more information than that. The mailer's log would likely be the only place for it, though you'd need root access to look at that. If it's a one off, you can likely ignore it.
