Почта не приходит на клиента, даже если её локально отправлять, но я вижу что на сервер она сама попадает поэтому отдаваемый заголовок привожу выше, в логах жалуется на 3 вещи  DSN: Local configuration error, Local configuration error и  (may be forged) did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA-SSL. Искал про "DSN: Local configuration error" - так и ничего не нашёл!

Прошу помощи с решение данной проблемы, перегуглил всё что возможно, но решения ни как не могу найти!
