TLSRPT stands for “TLS Report” or “TLS Reporting.” It’s a mechanism designed to help domain owners and email senders receive feedback about the status of email messages sent over Transport Layer Security (TLS) connections. TLS is a cryptographic protocol used to secure data transmission over networks, including the internet.
TLSRPT enables domain owners to receive reports on the success or failure of TLS connections established for email delivery. These reports can provide insights into the security and reliability of email communication between sender and recipient domains. They can help identify issues such as misconfigurations or vulnerabilities in TLS implementations.
By analyzing TLSRPT reports, organizations can ensure that email communication remains secure and encrypted during transmission, promoting the confidentiality and integrity of sensitive information.
