(PHP ActiveX) SMTP using SOCKS5, SOCKS4 Proxy

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// 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.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.MailMan')
$mailman = new COM("Chilkat.MailMan");

// 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->SocksHostname = 'www.mysocksproxyserver.com';
$mailman->SocksPort = 1080;
$mailman->SocksUsername = 'myProxyLogin';
$mailman->SocksPassword = 'myProxyPassword';
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$mailman->SocksVersion = 5;
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Set the SMTP server.
$mailman->SmtpHost = 'smtp.chilkatsoft.com';

// Set the SMTP login/password (if required)
$mailman->SmtpUsername = 'myUsername';
$mailman->SmtpPassword = 'myPassword';

// Create a new email object
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Email')
$email = new COM("Chilkat.Email");

$email->Subject = 'This is a test';
$email->Body = 'This is a test';
$email->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 != 1) {
    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 != 1) {
    print 'Connection to SMTP server not closed cleanly.' . "\n";
}

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