Affecting System - Royal 2 > Portal
The emails are legitimate, and were caused by our integration with our new WordPress Manager. WHMCS needs to basically communicate with your account to be able to manage and provision WP instances.
The emails weren't supposed to be sent though, as they should have been silently created. We're going to be disabling system notifications until we can get this problem fully resolved.
Affecting Server - Shared Royal-2
We are aware of a Spamhaus listing for our Royal 2 server, and are actively working with the datacenter to get this resolved as soon as possible. Until this has been resolved, email deliverability may be affected.
