Lua

SMTP using HTTP Proxy

Demonstrates how to communicate with an SMTP server via an HTTP proxy. Lua

local chilkat = require("chilkat")

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

-- The mailman object is used for sending and receiving email.
local mailman = chilkat.MailMan.new()

-- To connect through an HTTP proxy, set the HttpProxyHostname
-- and HttpProxyPort properties to the hostname (or IP address)
-- and port of the HTTP proxy.  Typical port numbers used by
-- HTTP proxy servers are 3128 and 8080.
mailman.http_proxy_hostname = "www.my-http-proxy.com"
mailman.http_proxy_port = 3128

-- Important:  Your HTTP proxy server must allow non-HTTP
-- traffic to pass.  Otherwise this does not work.

-- Set the SMTP server.
mailman.smtp_host = "smtp.chilkatsoft.com"

-- Set the SMTP login/password (if required)
mailman.smtp_username = "myUsername"
mailman.smtp_password = "myPassword"

-- Create a new email object
local email = chilkat.Email.new()

email.subject = "This is a test"
email.body = "This is a test"
email.from = "Chilkat Support <support@chilkatsoft.com>"
local success = email:add_to("Chilkat Admin", "admin@chilkatsoft.com")

-- Call SendEmail to connect to the SMTP server via the HTTP proxy and send.
-- The connection (i.e. session) to the SMTP server remains
-- open so that subsequent SendEmail calls may use the
-- same connection.
success = mailman:send_email(email)
if not success then
    print(mailman.last_error_text)
    return
end

-- Some SMTP servers do not actually send the email until
-- the connection is closed.  In these cases, it is necessary to
-- call CloseSmtpConnection for the mail to be  sent.
-- Most SMTP servers send the email immediately, and it is
-- not required to close the connection.  We'll close it here
-- for the example:
success = mailman:close_smtp_connection()
if not success then
    print("Connection to SMTP server not closed cleanly.")
end

print("Mail Sent!")
