Здравствуйте! При проверки почтовой системы на сервисе https://mxtoolbox.com/diagnostic.aspx получаю сообщение что почтовая система не является Open Ralay.
Но если выполняю следующие действия в TELNET, письмо в почтовый ящик приходит.
telnet smtp.domain.tld 25
HELO tester.domain.tld
MAIL FROM: nekto@gdeto.ru
RCPT TO: my@email.address
DATA
to: my@email.address
from: ktoto@hrenznaet.gde
subject: test
hehehe
.
QUIT
То есть любой может подключится по 25 порту и отправить письмо в почтовый ящик.
Как исправить данную ситуацию?
