Most email services will support TLS 1.2. The standard for TLS 1.3 has recently been agreed and should be adopted once available in popular email services. How TLS works
When you enter an email in the Secure Email Checker, we look to see if the email server supports inbound Transport Layer Security (TLS) encryption. If the email server supports TLS encryption, that means any message you send to that email address can't be snooped and is protected in transit. TLS email in operation. TLS is a cryptographic protocol that provides privacy and security between computer systems communicating over a network. Utilising public and private key encryption, TLS sets up a secure transport link between email servers on the Simple Mail Transfer Protocol (SMTP). The RFC 2246 document states the following: "The cryptographic parameters of the session state are produced by the TLS Handshake Protocol, which operates on top of the TLS Record Layer. Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, instant messaging, and voice over IP (VoIP). Websites can use TLS to secure all communications between

It is the basis of SSL (Secure Socket Layer) and TLS (Transport Layer Security). The latter is the newer version of the former, but everyone still uses the term SSL - although it does look a SMTP Email Delivery with TLS vs SSL - (New Research 2019) Jan 12, 2018
Most email services will support TLS 1.2. The standard for TLS 1.3 has recently been agreed and should be adopted once available in popular email services. How TLS works
Transport Layer Security (TLS) helps solve this issue by offering encryption technology for your message while it is "in transit" from one secure email server to another. That is, TLS helps prevent eavesdropping on email as it is carried between email servers that have enabled TLS protections for email. How does TLS work for an email? The mechanism and language (protocol) by which one email server sends an email message to another email server is called SMTP (Simple Mail Transport Protocol). For a long time now, email servers have had the choice of using TLS to transparently encrypt the message transmission from one server to the other. How does a TLS certificate work? When a user tries to connect to a server, the server sends them its TLS certificate. The user then verifies the server's certificate using CA certificates that are present on the user's device to establish a secure connection. Email is getting safer for you — provided that your mail service and your correspondent's both use a standard called "TLS," short for Transport Layer Security. Finally, Google and other We recommend using TLS in situations where you want to set up a secure channel of correspondence between Microsoft and your on-premises organization or another organization, such as a partner. Exchange Online always attempts to use TLS first to secure your email but cannot always do this if the other party does not offer TLS security.
