Send email via PHPMailer

I've organized the code like this:

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\SMTP;

require '/home/g/grablmz2/psywomenandmen.ru/public_html/ads/libs/PHPMailer/Exception.php';
require '/home/g/grablmz2/psywomenandmen.ru/public_html/ads/libs/PHPMailer/PHPMailer.php';
require '/home/g/grablmz2/psywomenandmen.ru/public_html/ads/libs/PHPMailer/SMTP.php';


$mail = new PHPMailer(true);

try {
    echo 'start';
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
    $mail->isSMTP();                                            // Send using SMTP
    $mail->Host       = 'smtp.gmail.com';                    // Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = 'hidden';                     // SMTP username
    $mail->Password   = 'hidden';                               // SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
    $mail->Port       = 587;                                    // TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above

    //Recipients
    $mail->setFrom('hidden', 'Mailer');
    $mail->addAddress('hidden', 'Michael');

   // Content
    $mail->Subject = 'Test';
    $mail->Body    = 'Test';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}

"Less Secure App" in Gmail is turned ON. Login and password are doublechecked by copying and pasting to the browser.

Did I do something wrong with ports and other options?

Solution

  • No, you did nothing wrong with ports and options, they're all fine. What you did wrong was not read the error message.

    This provides a link to a page that tells you more, and also a straightforward instruction: "Please log in via your web browser and then try again". What that means is that you should log into gmail via your browser, and only then try running your script again.

    There is a further step you might have to do involving gmail's unlock captcha page, but you'll find out about that by reading the PHPMailer troubleshooting guide that contains full details of this exact issue.
