A company's support team has received suspicious messages that seem to be from staff. The domain checks occasionally fail, and recipients worry about messages being altered. Which approach helps confirm that messages are authentic and intact?
A method that identifies valid outgoing mail hosts for a domain
A method that attaches cryptographic information to prove messages are unchanged
A framework that decides how to handle mail with mismatched data
An encryption feature that protects the contents between communicating parties
The option that attaches cryptographic information to each message is correct because it involves a signature that proves the sender is legitimate and the content has not been modified in transit. The record-based option identifies valid servers but does not confirm integrity. The policy framework provides instructions on handling mismatched messages but does not add a signature. The encryption feature secures the content but does not prevent sender identity spoofing.
