PHPMailer authentication error
Hello,
I'm setting up PHP Mailer to send emails from my website's form, but I'm receiving an authentication error.
I also tried creating an APP password for this account, but still not working.
The username /password are the same used to login into my dashboard.
Here is the code I'm using:
$mail->isSMTP();
$mail->Host = 'smtppro.zoho.com';
$mail->SMTPSecure = 'ssl';
$mail->Port='465';
$mail->SMTPAuth=true;
$mail->Username="myusername@domain.com";
$mail->Password="##REMOVED##"; //APP Password
$mail->SMTPOptions = array('ssl' => array('verify_peer' => false,'verify_peer_name' => false,'allow_self_signed' => true));
$mail->setFrom('contact@mywebsite.com', 'My Name);
$mail->addAddress("customeremail@email.com", "Cust Name"); // Add a recipient
$mail->isHTML(true);
$mail->Subject = "Website Form";
$mail->Body = "Message goes here...";
$mail->AltBody = 'You need a HTML email client to see this message';
$mail->send();
And this is the log:
