CodeIgniter 3 email not sending emails to other email servers but apple

Question

For some reason I'm just getting emails to apple emails but gmail, Microsoft etc. I'm using my own smtp server with SSL, I checked SPF and there is no problems. I also checked headers and etc.

I also try using PHPMailer but only sends with gmail smtp. Any help or direction to fix this issue will be very appreciated!

function send_mail($to, $subject, $message) {
    $CI = get_instance();
    
    $email_library = get_email_library();

    if($email_library == 'codeigniter'){
        $email_config = Array();
        $email_config["protocol"] = "smtp";
        $email_config["charset"] = "utf-8";
        $email_config["mailtype"] = "html";
        $email_config["smtp_host"] = smtp_host();
        $email_config["smtp_port"] = smtp_port();
        $email_config["smtp_user"] = smtp_email();
        $email_config["smtp_pass"] = smtp_password();
        $email_config["smtp_crypto"] = smtp_encryption();
        if($email_config["smtp_crypto"] == 'none'){
            $email_config["smtp_crypto"] = "";
        }
        $CI->load->library('email', $email_config);
        $CI->email->clear(true);
        $CI->email->set_newline("\r\n");
        $CI->email->set_crlf("\r\n");
        $CI->email->from(from_email(), company_name());
        $CI->email->to($to);
        $CI->email->subject($subject);
        $CI->email->message($message);
        if($CI->email->send()){
            return true;
        }else{
            return false;
        }
    }else{
        require_once('vendor/phpmailer/class.phpmailer.php');
        $CI = new PHPMailer(); 
        $CI->IsSMTP(); 
        $CI->SMTPDebug = 1; 
        $CI->SMTPAuth = true;

        $CI->Password = smtp_password();
        $CI->SetFrom(from_email());
        $CI->Subject = $subject;
        $CI->Body = $message;
        $CI->AddAddress($to);
        if($CI->Send()){
            return true;
        }else{
            return false;
        }
    }
