вот здесь видимо и порылась собака :)

видите nata.vova.linux.nt(OK) ? скорей всего сендмейл настроен НЕ
получать писем от хостов которые не прописаны толком в ДНС (отсутствует
обратная запись PTR )

в оригинальном письме имеем

logging access from: [ 192.168.15.4](FAIL)

то есть отработала нормальная в принципе антиспамерская тактика

чтобы решить проблему скорей всего надо прописать 192,168,15,4 в ДНС
аналогичным образом как и для 192,168,16,2

что-то типа

192,168,16,2    IN      PTR     somehost.somedomain.ru

и отвечать лучше в рассылку :)

ОК спасибо

с этим вопросов нет
но проблема осталась:

sergey:~# telnet vova.vova.linux.nt 25
Trying 192.168.17.1...
Connected to vova.vova.linux.nt.
Escape character is '^]'.
220 ;; ESMTP connection timed out; no servers could be reached Sendmail 8.13.7/8.13.7/Debian-2; Tue, 12 Sep 2006 11:43:19 +0300; (No UCE/UBE) logging access from: host200.vova.linux.nt(OK)-host200.vova.linux.nt [192.168.17.200]

Вот это 220 ;; ESMTP connection timed out; no servers could be reached Sendmail и мешает отправлять почту

боролся долго и наконец решил:
