PhpMailer + Postmark "connect() failed"

After following the instructions on randy's blog-post and the instructions from postmark i still don't get the mail send.

Here's my code:


    $mail = new PHPMailer();

        $mail->SMTPAuth = true;
    $mail->Host = "smtp.postmarkapp.com";
    $mail->Port = 2525;
    $mail->Username = "API-Key";
    $mail->Password = "API-Key";
    $mail->SMTPDebug = 1;

    $mail->addAddress('mymail@gmail.com', 'John Doe');

    $mail->Subject = 'PHPMailer mail() test';


    if (!$mail->send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;

    header("Location: contact.php?status=thanks");

This is the Error i get:

SMTP ERROR: Failed to connect to server: Connection timed out (110) 2014-08-30 11:57:42 SMTP connect() failed. Mailer Error: SMTP connect() failed.

What's wrong here? The SMTP is enabled on Postmark.

Did you try other ports like 25 or 587? Are you making sure that your api key is correct with no spaces on at the beginning or end?

Yeah it is. Also when i used this code to send a mail from my local apache server...it worked.

Could this be a problem with the hosting site? That i need some kind of authentification or signature?? The website is hostet at hostinger.in.

yes. your host could be blocking the smtp ports. I would call them or start a support ticket to find out.
