  • Plesk for Linux

Question

How to install PHPMailer manually in Plesk for Linux?

Answer

  1. Connect to the server via SSH

  2. Download PHPMailer and unzip the archive:

    # wget https://github.com/PHPMailer/PHPMailer/archive/master.zip
    # unzip master.zip

  3. Move PHPMailer to the necessary location, for example:

    # mv PHPMailer-master/ /var/www/vhosts/example.com/

  4. Add this location to include_path in Domains > example.com > PHP Settings:

    Note: do not remove existing path; to separate directories, add a colon (:) between them, for example:
    .:/usr/share/php:/usr/share/pear:/var/www/vhosts/example.com/

  5. Modify the existing PHP script used for sending mail, for example:

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

    use PHPMailerPHPMailerPHPMailer;
    use PHPMailerPHPMailerException;
    //Load Composer's autoloader
    require 'vendor/autoload.php';
    $mail = new PHPMailer(true); // Passing true enables exceptions
    try {
    //Server settings
    $mail->SMTPDebug = 2; // Enable verbose debug output
    $mail->isSMTP(); // Set mailer to use SMTP
    $mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup SMTP servers
    $mail->SMTPAuth = true; // Enable SMTP authentication
    $mail->Username = '[email protected]'; // SMTP username
    $mail->Password = 'secret'; // SMTP password
    $mail->SMTPSecure = 'tls'; // Enable TLS encryption, ssl also accepted
    $mail->Port = 587; // TCP port to connect to
    //Recipients
    $mail->setFrom('[email protected]', 'Mailer');
    $mail->addAddress('[email protected]', 'Joe User'); // Add a recipient
    $mail->addAddress('[email protected]'); // Name is optional
    $mail->addReplyTo('[email protected]', 'Information');
    $mail->addCC('[email protected]');
    $mail->addBCC('[email protected]');
    //Attachments
    $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
    $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
    //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->AltBody = 'This is the body in plain text for non-HTML mail clients';
    $mail->send();
    echo 'Message has been sent';
    } catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
    }
