Comment 1 for bug 670683

It is a bug. In order to communicate with smtp.gmail.com, 'SMTPSecure' parameter in phpmailer has to be set either to 'ssl' (and smtp port set to 465) or 'tls' (and port set to 587). Currently SMTPSecure is not configured through mahara configuration file.

Will fix this on master in a moment.
