SMTP using SOCKS5, SOCKS4 Proxy

Demonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 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 use a SOCKS4 or SOCKS5 proxy, simply set the following
-- properties prior to making any calls that communicate with
-- an SMTP server:
-- The SOCKS hostname may be a domain name or
-- IP address:
mailman.socks_hostname = "www.mysocksproxyserver.com"
mailman.socks_port = 1080
mailman.socks_username = "myProxyLogin"
mailman.socks_password = "myProxyPassword"
-- Set the SOCKS version to 4 or 5 based on the version
-- of the SOCKS proxy server:
mailman.socks_version = 5
-- Note: SOCKS4 servers only support usernames without passwords.
-- SOCKS5 servers support full login/password authentication.

-- 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 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!")
