I noticed that email notifications are not being received for new private messages etc. Email notifications are enabled in my profile and the WHM panel shows that the email has been sent. Yet no emails are being received in my main inbox or in my spam folder.
My first thought was that this was either a hosting configuration issue or a DNS issue. The reason that I believe this could be something to do with XenForo is because emails are being received correctly through the contact form in WordPress (via the front end of the site).
I have another XenForo forum hosted by another company and the configuration settings are identical, so I am unsure as to whether hosting settings are the problem.
Does XenForo require anything to be modified in order to send emails correctly? I am unsure as to whether one host has changed my XenForo setup in order to send emails correctly and the other host hasn't.
Any help on this would be appreciated (particularly from those who also use a third-party DNS service)
