SMTP

Отправляется но не приходит почта, почему?

Поставил чудо панельку brainycp.
Все настроил, все четко встало, но почта с мира не доходит.
при этоу уходит идеально.

Пробую стучать на 25 порт из вне и с нутри:
ответ один

Connected to youmail.my-mails.ru.
Escape character is '^]'.
220 youmail.my-mails.ru, ESMTP EXIM 4.92.3
421 youmail.my-mails.ru: SMTP command timeout - closing connection
Connection closed by foreign host.

попробовал изнутри telnet 127.0.0.1 25 и 78.108.88.73 25
аналогично .........SMTP command timeout - closing connection...............

постучался телнетом на 110 порт - все ок

Trying 78.108.88.73...
Connected to youmail.my-mails.ru.
