Email

The fields and tags in the Email data model describe email traffic, whether server:server or client:server.

Note: A dataset is a component of a data model. In versions of the Splunk platform prior to version 6.5.0, these were referred to as data model objects.

Tags used with Email event datasets

The following tags act as constraints to identify your events as being relevant to this data model. For more information, see How to use these reference tables.
