Добрый день All
Появилась одна странная проблема при обмене письмами с одним единственным адресатом
Коротко конфигурация почтовой схемы такая Exchange ( ящики ) - FreeBSD (Sendmail)(внешний релей)

Проблема в том что есть один адрес strl@spb.baltika.ru  -  пивоваренный завод, тот самый между прочим :)

Обмен письмами без вложений с данным адресатом не вызывает проблем и происходит в штатном режиме, но как только пользователь из моей сети начинает отсылать письмо с вложением то происходит следующее:

1) пользователю приходит отлуп

Вопрос ...почему это происходит? у кого косяк?
Да еще, у ребят в Балтике стоит Лотус , не знаю как это может повлиять имхо никак..
Со всеми остальными доменами обмен почтой происходит абсолютно нормально как с вложениями так и без.
Мой сервер принимает от них письма так же и с вложениями и без них
