Iterate Email Headers

Demonstrates how to iterate over the email header fields. Lua

local chilkat = require("chilkat")

local email = chilkat.Email.new()

-- First, load an email from a file.
-- Note: an email object may be loaded from a file, or
-- downloaded directly from a POP3 or IMAP server...

local success = email:load_eml("testReceivedHdrs.eml")
if not success then
    print(email.last_error_text)
    return
end

-- How many header fields?
local n = email.num_header_fields
if n > 0 then
    -- Display the name and value of each header:
    local name = ""
    local value = ""
    for i = 0, n - 1 do
        name = email:get_header_field_name(i)
        value = email:get_header_field_value(i)
        print(i)
        print(name)
        print(value)
    end
end
