SMTA) operates in accordance with this specification and provides a secure end-to-end channel for sending email over unsecured networks. The MTA-STS protocol allows an SMTP client to verify server identity and ensure that it is not connecting to an impostor by requiring the server to provide its certificate fingerprint in the TLS handshake. The client then verifies the certificate against a trust store containing certificates of known servers. The Need for Shifting to Enforced TLS Encryption.
STARTTLS was not perfect, and it failed to address Job Function Email List two major problems: the first being that it is an optional measure, hence STARTTLS fails to prevent man-in-the-middle (MITM) attacks. This is because an MITM attacker can easily modify a connection and prevent the encryption update from taking place. The second problem with it is that even if STARTTLS is implemented, there is no the identity of the sending server as SMTP mail servers do not validate certificates. While most outgoing emails today are secured.
With Transport Layer Security (TLS) encryption, an industry standard adopted even by consumer email, attackers can still obstruct and tamper with your email even before it gets encrypted. If you email to transport your emails over a secure connection, your data could be compromised or even modified and tampered with by a cyber attacker. Here is where MTA-STS steps in and fixes this issue, guaranteeing safe transit for your emails as well as successfully mitigating MITM attacks.
