Can someone please help with an email notification issue? All of a sudden emails notifications stopped working.
After reporting this issue I received no additional messages
Alert description: Notification subsystem failed

'Smtp' protocol to xx
Microsoft.EnterpriseManagement.HealthService.Modules.Notification.SmtpNotificationException:
Service not available, closing transmission channel. The server response was:

SMTP Channel is pointing to the exchange NLB and return address is a valid return address. I am currently using a Anonymous authentication.
Exchange - I have a relay that accepts anonymous authentication with the servers IP address.
