We are experiencing issues with our Mail-on Server, which some customers use to relay outbound mail for.
We are seeing outbound mail being deferred by the Mail-on Server.
This has now been resolved and monitored on our side.
Please remove the Mail-on server as a relay for your outbound mail. You can do this by disabling the smart host under System Set Up < Mail relay < Outbound < Smart Host.
