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

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

$mailman->MailHost = 'pop.gmail.com';
$mailman->MailPort = 995;
$mailman->PopSsl = 1;

$mailman->PopUsername = 'my_account@gmail.com';

// If using OAuth2 authentication, leave the password empty.
$mailman->PopPassword = '';

// Load our previously obtained OAuth2 access token.
// See Getting a GMail POP3 OAuth2 Access Token
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jsonToken = new COM("Chilkat.JsonObject");
$success = $jsonToken->LoadFile('qa_data/tokens/gmail_pop3.json');
if ($success == 0) {
    print $jsonToken->LastErrorText . "\n";
    exit;
}

$mailman->OAuth2AccessToken = $jsonToken->stringOf('access_token');

// Make the TLS connection to the POP3 server.
$success = $mailman->Pop3Connect();
if ($success != 1) {
    print $mailman->LastErrorText . "\n";
    exit;
}

// Authenticate..
$success = $mailman->Pop3Authenticate();
if ($success != 1) {
    print $mailman->LastErrorText . "\n";

// Find out how many emails are on the server..
$numEmails = $mailman->CheckMail();

// Examine the POP3 session log:
print $mailman->Pop3SessionLog . "\n";

// The POP3 session log will look something like this:

// **** Connected to pop.gmail.com:995
// < +OK Gpop ready for requests from 87.9.200.42 l16mb86351205iok
// > AUTH XOAUTH2 dXNlcj1....VaMDJFAQE=

// -- Finished.

// End the POP3 session and close the connection to the GMail server.
