Chilkat Lua Downloads

Lua
local chilkat = require("chilkat")

-- The AddHeaderField can be called to add any header field.
-- If the header field already exists, AddHeaderField replaces it.
local email = chilkat.Email.new()
email:add_header_field("X-Priority", "3 (Normal)")

email:add_header_field("X-Priority", "1 (High)")

email:add_header_field("X-Priority", "5 (Low)")

-- The X-Priority value ranges from 1 to 5, with 1 being
-- high priority, 3 is normal, and 5 is low.
-- You may set X-Priority to the number alone:

email:add_header_field("X-Priority", "1")

-- Including extra text, such as (High), should not
-- affect how the header is interpreted.
email:add_header_field("X-Priority", "1 (High)")
