### Basic Email Sending with PHPMailer

Source: https://github.com/dependabot/smoke-tests/blob/main/composer/vendor/phpmailer/phpmailer/README.md

This example demonstrates how to send an email using PHPMailer with SMTP authentication, including setting recipients, CC/BCC, attachments, and HTML content. Ensure you have PHPMailer installed via Composer or included in your include_path.

```php
<?php
require 'class.phpmailer.php';

$mail = new PHPMailer;

$mail->IsSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup server
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'jswan';                            // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable encryption, 'ssl' also accepted

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->AddAddress('josh@example.net', 'Josh Adams');  // Add a recipient
$mail->AddAddress('ellen@example.com');               // Name is optional
$mail->AddReplyTo('info@example.com', 'Information');
$mail->AddCC('cc@example.com');
$mail->AddBCC('bcc@example.com');

$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 = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->Send()) {
   echo 'Message could not be sent.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;
   exit;
}

echo 'Message has been sent';

Source: https://github.com/dependabot/smoke-tests/blob/main/composer/vendor/phpmailer/phpmailer/docs/Note_for_SMTP_debugging.txt

Set the `SMTPDebug` property to a value of 1 or 2 to enable debugging. This will output errors and messages to help diagnose SMTP connection issues. Remember to disable debugging before deploying to production.

```php
$mail->SMTPDebug = 1;
$mail->IsSMTP();  // telling the class to use SMTP
$mail->SMTPAuth   = true;                // enable SMTP authentication
$mail->Port       = 26;                  // set the SMTP port
$mail->Host       = "mail.yourhost.com"; // SMTP server
$mail->Username   = "name@yourhost.com"; // SMTP account username
$mail->Password   = "your password";     // SMTP account password
```

--------------------------------
