How to Fix WordPress SMTP Issues with iCloud Custom Domain

Troubleshooting Email Delivery Problems with iCloud and WordPress

I have just begun to use the iCloud+ Custom Domain. The emails are sent by my WordPress-powered website and are fully connected to my GoDaddy domain, but they are not reaching their intended recipient.

The SMTP setups could be to blame for this. To ensure that my emails are received, I purchased WPMailSMTP to handle the SMTP validation with iCloud+. Any assistance would be greatly valued.

Command	Description
use PHPMailer\PHPMailer\PHPMailer;	Contains the PHPMailer class, which is used to deliver emails via SMTP.
require 'vendor/autoload.php';	Uses Composer's autoload functionality to load all required libraries and dependencies.
$mail->isSMTP();	Configures PHPMailer to deliver emails via SMTP.
$mail->Host	Gives the SMTP server that needs to be connected to.
$mail->SMTPAuth	Enables SMTP authentication.
$mail->SMTPSecure	Sets the TLS/SSL encryption system to use.
$mail->Port	Gives the SMTP server's port number to be connected to.
$mail->setFrom	Sets the email address and name of the sender.
$mail->isHTML(true);	Shows that the body of the email is formatted in HTML.
$mail->AltBody	Sets the email's alternative body to plain text for clients that do not support HTML.

WordPress iCloud+ Custom Domain SMTP Implementation

The scripts made in the aforementioned examples are intended to set up SMTP parameters so that emails can be sent from a WordPress website with an iCloud+ custom domain. The first script makes advantage of the well-known PHP email sending library . To load dependencies, it begins by including the required classes with and . Next, it uses $mail->isSMTP(); to configure the SMTP server and to designate the iCloud SMTP server. The app-specific password is supplied, and is used to enable authentication. Additionally, the script uses to set encryption to TLS and $mail->Port to specify the port.

The recipient's address is inserted, and the email sender's address is set to . The script uses to indicate that the email content is in HTML format and to give an alternate plain text body. With this configuration, emails are sent through iCloud's SMTP server correctly. The second example shows how to set up the WordPress dashboard's WPMailSMTP plugin. To ensure that the settings meet iCloud's standards for successful email delivery, navigate to the plugin settings, select "Other SMTP," and fill in the SMTP details (host, encryption, port, username, and password).

//php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'vendor/autoload.php';
$mail = new PHPMailer(true);
try {
    $mail->isSMTP();
    $mail->Host       = 'smtp.mail.me.com';
    $mail->SMTPAuth   = true;
    $mail->Username   = 'your_custom_domain_email';
    $mail->Password   = 'your_app_specific_password';
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
    $mail->Port       = 587;
    $mail->setFrom('your_custom_domain_email', 'Your Name');
    $mail->addAddress('recipient@example.com');
    $mail->isHTML(true);
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body in bold!';
    $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}";
}
