There are many different forms where data can be entered and I would like to not go control by control by form and create is Valid etc per item. I see that most related posts deal with Web Apps and/or mention Enterprise Library Validation Application Block.

When there's a problem delivering a message, Exchange sends an NDR to the message sender that indicates there was a problem.

NDRs include a code that indicates why the message wasn't delivered, and possible solutions to help get the message delivered.

For procedures related to NDRs in Exchange 2016, see Procedures for DSNs and NDRs in Exchange 2016.
