local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local mailman = chilkat.MailMan.new()

mailman.smtp_host = "smtp.mail.us-west-2.awsapps.com"
mailman.smtp_ssl = true
mailman.smtp_port = 465

local success = mailman:smtp_connect()
if not success then
    print(mailman.last_error_text)
    return
end

mailman.smtp_username = "john@example.com"
mailman.smtp_password = "the_password"

success = mailman:smtp_authenticate()
if not success then
    print(mailman.last_error_text)
    return
end

print("Authenticated!")

-- Send the "EHLO" command again to get the multi-line response that includes the SMTP capabilities.
-- The capabilities are the lines in the response that begin with "250-".
local responseStr = mailman:smtp_send_raw_command("EHLO client.example.com", "utf-8", false)
if not mailman.last_method_success then
    print(mailman.last_error_text)
    return
end

print(responseStr)

-- A sample response:
