phpmailerHow can I use PHPMailer to send emails with a Yahoo account?

To use PHPMailer to send emails with a Yahoo account, you will need to set the SMTP host, port, and authentication settings. Here is an example code block to do so:

<?php
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Load Composer's autoloader
require 'vendor/autoload.php';

// Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = 2;                                       // Enable verbose debug output
    $mail->isSMTP();                                            // Set mailer to use SMTP
    $mail->Host       = 'smtp.mail.yahoo.com';                  // Specify Yahoo SMTP server
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = 'YOUR_YAHOO_EMAIL_ADDRESS';             // SMTP username
    $mail->Password   = 'YOUR_YAHOO_EMAIL_PASSWORD';             // SMTP password
    $mail->SMTPSecure = 'tls';                                  // Enable TLS encryption, `ssl` also accepted
    $mail->Port       = 587;                                    // TCP port to connect to

    //Recipients
    $mail->setFrom('YOUR_YAHOO_EMAIL_ADDRESS', 'Your Name');
    $mail->addAddress('RECIPIENT_EMAIL_ADDRESS', 'Recipient Name');     // Add a recipient

    // Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';

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

This example code block will set the SMTP host to smtp.mail.yahoo.com, enable SMTP authentication, set the username and password to your Yahoo email address and password, set the encryption to TLS, and set the port to 587. The code will also set the sender and recipient email addresses, set the subject and body of the email, and send the email. If the email is successfully sent, the output will be Message has been sent.
