Demonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 proxy. PHP Extension

<?php

include("chilkat.php");

$success = false;

// 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.
$mailman = new CkMailMan();

// 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->put_SocksHostname('www.mysocksproxyserver.com');
$mailman->put_SocksPort(1080);
$mailman->put_SocksUsername('myProxyLogin');
$mailman->put_SocksPassword('myProxyPassword');
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$mailman->put_SocksVersion(5);
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Set the SMTP server.
$mailman->put_SmtpHost('smtp.chilkatsoft.com');

// Set the SMTP login/password (if required)
$mailman->put_SmtpUsername('myUsername');
$mailman->put_SmtpPassword('myPassword');

// Create a new email object
$email = new CkEmail();

$email->put_Subject('This is a test');
$email->put_Body('This is a test');
$email->put_From('Chilkat Support <support@chilkatsoft.com>');
$success = $email->AddTo('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 = $mailman->SendEmail($email);
if ($success != true) {
    print $mailman->lastErrorText() . "\n";
    exit;
}

// 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 = $mailman->CloseSmtpConnection();
if ($success != true) {
    print 'Connection to SMTP server not closed cleanly.' . "\n";
}

print 'Mail Sent!' . "\n";
