I've moved my app over to digitalocean but my notifications aren't working. I'm using Ubuntu. I'm using php mailer and using the following function function sendEmail($subject, $body, $altbody, $fromEmail, $fromName, $replyToEmail, $to, $cc, $bcc) { $mail = new PHPMailer; $mail->IsSMTP(); // Set mailer to use SMTP $mail->Host = 'smtp.gmail.com'; // Specify main and backup server $mail->SMTPAuth = true; // Enable SMTP authentication $mail->Username = 'GMAIL ADDRESS'; // SMTP username $mail->Password = 'PASSWORD'; // SMTP password $mail->SMTPSecure = 'tls'; // Enable encryption, 'ssl' also accepted $mail->From = $fromEmail; $mail->FromName = $fromName; //$mail->AddAddress('RECIPIENT EMAIL'); // Add a recipient $mail->AddReplyTo($replyToEmail); $mail->AddAddress($to); // Name is optional $mail->AddCC($cc); $mail->AddBCC($bcc); $mail->WordWrap = 50; // Set word wrap to 50 characters //$mail->AddAttachment('/var/tmp/file.tar.gz'); // Add attachments //$mail->AddAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name $mail->IsHTML(true); // Set email format to HTML $mail->Subject = $subject; $mail->Body = $body; $mail->AltBody = $altbody; if(!$mail->Send()) { echo 'Message could not be sent.'; echo 'Mailer Error: ' . $mail->ErrorInfo; exit; } else { echo "Message has been sent"; } but I'm getting the error "Message could not be sent.Mailer Error: SMTP Connect() failed.thorn@BlackThorn:~$ " What should I be using?
