SMTP/POP3 Enable/Disable TLS 1.3

See more POP3 Examples

Chilkat started supporting TLS 1.3 in version 9.5.0.82. For versions 9.5.0.82 and 9.5.0.83, TLS 1.3 was not enabled by default. A program could enable TLS 1.3 by including the "EnableTls13" keyword in the UncommonOptions property.

In Chilkat v9.5.0.84 and later, TLS 1.3 is enabled by default. TLS 1.3 can be disabled by including the "DisableTls13" keyword in UncommonOptions. This will cause TLS 1.2 to be used instead.
