PHPMailer SMTP works on local server, but not on production server

Question

I have the following configuration for PHPMailer, which worked perfectly on my localhost machine, but doesn't send emails in production:

//Send a notification email
try {
    $mail = new PHPMailer(true);
    $mail->IsSMTP();
    $mail->SMTPDebug = 0;
    $mail->SMTPAuth = true;
    $mail->SMTPSecure = "tls";
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 587;
    $mail->Username = $username;
    $mail->Password = $password;
    $mail->AddAddress($_POST['username'], $name);
    $mail->SetFrom("no-reply@a-domain-setup-in-google-apps.com", "No-Reply");
    $mail->Subject = $subject;
    $mail->AltBody = $altBody;
    $mail->MsgHTML($bodyHTML);
    $mail->Send();
} catch (phpmailerException $e) {
    echo $e->errorMessage();
    exit;
} catch (Exception $e) {
    echo $e->getMessage();
    exit;
}

When I set SMTP debug equal to 2 , here is what I get:

SMTP -> FROM SERVER:220 mx.google.com ESMTP bo7sm9593967igb.2 
SMTP -> FROM SERVER: 250-mx.google.com at your service, [204.93.159.80] 250-SIZE 35882577 250-8BITMIME 250-STARTTLS 250-ENHANCEDSTATUSCODES 250 PIPELINING

SMTP -> FROM SERVER:250 2.0.0 OK 1341071123 bo7sm9593967igb.2

It all looks good, but I can't send emails any more.

I am positive my Google Apps account that this is sending emails from is configured properly (as it worked before), and my logon credentials are correct.

Any ideas?

Answer 1

Your emails are most likely not delivering because .co.cc domains are associated with spam and generally non-legitimate sites; Google has banned all .co.cc domains from its index .

It would thus make sense that they are blocking or heavily filtering emails from these domains as well.

Consider using a normal domain, like one ending with .com .
