Как я могу отправлять электронные письма, используя электронную почту godaddys office 365 и цифровую морскую каплю?

Мне нужен наш сервер приложений для отправки электронной почты нашим клиентам через почтовый сервер, размещенный на Goddady

Мы используем в качестве ссылки случай, описанный в https://www.digitalocean.com/community/questions/how-to-solve-emails-problems-after-site-is-migrated-to-digital-ocean

мы добавляем записи MX, но рассылка не работает; мы прилагаем ошибки репортера библиотекой, которую мы используем:

ТЕХНИЧЕСКИЕ ДАННЫЕ

• ОС: Ubuntu 16.07
• Язык: PHP 7.2
• библиотека почты: phpmailer 6.0.5

АКТУАЛИЗАЦИЯ

новая конфигурация:

$mail->SMTPDebug = 4;
$mail->isSMTP();
$mail->DKIM_domain = '127.0.0.1';
$mail->Host =  'smtpout.secureserver.net';
$mail->SMTPAuth = true;
$mail->Username = MAIL_APP1;
$mail->Password = MAIL_APP1_PWD;
$mail->SMTPSecure = 'ssl';
$mail->Port = 465; //SMTP_PORT;

новая ошибка:
