We are currently experiencing a high level of emails through our network at the moment which may prevent some customers from receiving messages. Our level 2 support technicians are working to fix this issue.
We had a backlog of messages on the server overnight which caused the delay.
Customers are now reporting that emails are now being received
UPDATE: New hardware has been installed on the affected server if you continue to have issues please send an email to support@ozwebhost.com.au
