Are there specific PHP functions or libraries recommended for interacting with email servers?

When interacting with email servers in PHP, it is recommended to use the built-in `IMAP` extension for handling incoming emails and `PHPMailer` library for sending emails. These tools provide robust functionality and support for various email protocols, making it easier to interact with email servers securely and efficiently. 

// Example using IMAP extension to fetch emails
$hostname = '{mail.example.com:993/imap/ssl}INBOX';
$username = 'email@example.com';
$password = 'password';

$mailbox = imap_open($hostname, $username, $password) or die('Cannot connect to mailbox: ' . imap_last_error());

$emails = imap_search($mailbox, 'ALL');

foreach ($emails as $email_number) {
    $email_header = imap_headerinfo($mailbox, $email_number);
    echo 'From: ' . $email_header->fromaddress . '<br>';
    echo 'Subject: ' . $email_header->subject . '<br>';
}

imap_close($mailbox);

// Example using PHPMailer library to send emails
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'email@example.com';
    $mail->Password = 'password';
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
    $mail->Port = 587;

    $mail->setFrom('email@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Test Email';
    $mail->Body = 'This is a test email sent using PHPMailer.';

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