I am using Google Apps to power email for the domain, and to prevent being marked as spam, have configured XenForo to send mails through Google's SMTP servers. However, emails aren't being sent. I am certain it is configured properly, and have tested it with equivalent settings using PHPMailer on the server, which was able to send them fine. When I test is with a contact email in XenForo, no errors are given, but yet the email is not received. I'm not sure if this is a bug in the software, or what could be preventing them from being sent, but I would appreciate any help or information on the problem. Thanks.
