How to avoid a mismatch between email body and PDF attachment in eMessaging in EngageOne Digital Delivery

Product Feature: General
There is a feature in eMessaging, called "Content Verification", which will force eMessaging to perform additional checks to verify that correct PDF attachment is inserted into each email. 

For example, have eMessaging check the DocInstanceId embedded in the generated PDF file against the value provided in the DIJ for the message being processed.

This feature is available within Outbound Profile setting screen.
