What are the potential reasons for emails sent using the mail function not appearing in the webmail sent folder?

The emails sent using the mail function may not appear in the webmail sent folder due to the fact that the mail function sends emails directly from the server, bypassing the webmail client. To solve this issue, you can use SMTP to send emails through the webmail server, which will then save the emails in the sent folder. 

// Set the SMTP server and port
ini_set('SMTP', 'smtp.yourwebmailserver.com');
ini_set('smtp_port', 25);

// Set the sender and recipient email addresses
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email";
$headers = "From: sender@example.com";

// Send the email using SMTP
if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully using SMTP";
} else {
    echo "Email sending failed";
}
