Encryption Protocols
Yes, it is confusing. SSL, TLS, and SSL/TLS, are terms that are used interchangeably by many email client configurations and on many web pages but those terms are not the same.

SSL is an acronym for the 'Secure Sockets Layer' protocol introduced by Netscape in 1994. The SSL protocol provided mechanism for a client and server to negotiate a common encryption scheme to provide an encrypted connection between the client and the server. There are two versions of SSL in use, SSLv2(SSL 2.0) and SSLv3(SSL 3.0), both of which are deprecated due to security vulnerabilities. SSLv2 was introducted shortly after the initial SSL procotol specification due to security flaws in the initial specification.

TLS is an acronym for 'Transport Layer Security'. There are four TLS versions in use, TLS1.0, TLS1.1, TLS1.2, and TLS1.3. TLS1.0 and TLS1.1 are insecure but they are still widely in use for interoperability. The argument is that poor encryption is better than none.

Some ports in the table above allow a clear text session that can be upgraded to a encrypted session. STARTTLS is a protocol specification providing a mechanism to negotiate and upgrade a clear text TCP connection to an encrypted connection between the client and the server. STARTTLS is an acronym for 'Start TLS Negotiation'.

The IMAP/POP3 server name mail.mxes.net supports TLS1.0, TLS1.1, and TLS1.2 over IPv4 plus TLS1.3 over IPv6.

The IMAP/POP3 server name sslv3.mxes.net still supports SSLv3 for customers using custom software that can not be updated. This server should not be used unless absolutely necessary.

The SMTP server name smtp.mxes.net supports TLS1.0, TLS1.1, TLS1.2, and TLS1.3 over IPv4 and IPv6.

MX Servers
If we are hosting email for your domain, the MX record for your domain should point to our MX server cluster name at any priority:
mxin.mxes.net
That name resolves to multiple IP addresses for our MX servers.
