(PHP ActiveX) SMTP XOAUTH2 Authentication

Demonstrates how to authenticate using an OAuth2 access token. This example assumes you have already obtained the access token and now wish to use it in an SMTP session.

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.

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

$oauth2_access_token = 'some_previously_obtained_token';

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.MailMan')

// Set the properties for the SMTP server, whatever they may be..

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

$email->Subject = 'This is a test';
$email->Body = 'This is a test';
$email->From = 'Joe Example <joe@example.com>';
$email->AddTo('Chilkat Admin','admin@chilkatsoft.com');

// Connect to the server indicated by the SmtpHost property
$success = $mailman->SmtpConnect();
if ($success != 1) {
    print $mailman->LastErrorText . "\n";

// Authenticate using XOAUTH2 (using the OAuth2AccessToken)
