Поднимаю сервер впервые.  Все делала по статье. Столкнулась с такой ошибкой, точнее даже рядом ошибок:
telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mail.nes.odessa.ua ESMTP
helo localhost
250 mail.nes.odessa.ua
mail from: 111@nes.odessa.ua
250 2.1.0 Ok
RCPT TO: natali@sct.odessa.ua
451 4.3.0 <natali@sct.odessa.ua>: Temporary lookup failure

В логах целый букет:
