Lua Requires Chilkat v9.5.0.82+

SMTP/POP3 Enable/Disable TLS 1.3

See more POP3 Examples

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.

Lua

local chilkat = require("chilkat")

local mailman = chilkat.MailMan.new()

-- In Chilkat v9.5.0.82 and .83, TLS 1.3 is not enabled by default.
-- To enable TLS 1.3, add the keyword "EnableTls13" to the UncommonOptions property.
mailman.uncommon_options = "EnableTls13"

-- In Chilkat v9.5.0.84 and later, TLS 1.3 is enabled by default.
-- If disabling TLS 1.3 is needed (for some unanticipated reason), then add the keyword
-- "DisableTls13" to UncommonOptions
mailman.uncommon_options = "DisableTls13"
