Symptoms:

Event ID: 3506
Type: Error
Source: MMSender
Description: Failed to generate notification

Causes:

The MailMarshal SMTP Sender service is unable to deliver a message. MailMarshal is also unable to generate a notification to the original sender that the message delivery failed.

If the MailMarshal service is unable to generate and send a notification, this event will be raised.
