Sending E‑Mail Using PHPMailer

PHPMailer is a popular PHP library that makes it easier to send e‑mail messages with advanced features such as SMTP authentication, HTML formatting, and attachments. On ruachost.com, PHPMailer is supported and can be installed via Composer or Git.

???? Important Hosting Restrictions

• On Shared Hosting and Reseller Hosting, you cannot use external SMTP servers.
• You must send e‑mail through ruachost.com servers.
• Other hosting packages (Managed VPS, Dedicated) allow external SMTP servers.

Installing PHPMailer

Option 1: Using Composer

composer require phpmailer/phpmailer

Option 2: Using Git

git clone https://github.com/PHPMailer/PHPMailer.git

Example: Sending E‑Mail with PHPMailer

<?php
use PHPMailer\PHPMailer\PHPMailer;
require 'vendor/autoload.php';

$mail = new PHPMailer();
$mail->isSMTP();
$mail->Host = gethostname();   // Use ruachost.com servers for shared/reseller/WordPress hosting
$mail->SMTPAuth = true;
$mail->Username = 'sender@example.com';
$mail->Password = 'password';
$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com');
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the body.';

if(!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}
?>
