Имеется почтовик на постфиксе, давно и успешно трудящийся, но вот с недавних пор от одного адресата перестал получать почту.
Т.е. от нас ему почта идёт, а его почта у нас откидывается с сообщением:

May 16 13:29:32 BSD postfix/smtpd[91940]: NOQUEUE: reject: RCPT from unknown[195.64.192.153]: 550 5.7.1 Client host rejected: cannot find your hostname, [195.64.192.153]; from=<adresat@ubrr.ru> to=<adress@mydomain.ru> proto=ESMTP helo=<relay.ural.ru>
На сервере пробовал адреса DNS сервера менять на гугловый, на яндексовый, на провайдерский. Пока тупо добавил в access_client ip адрес релея, но хочу понять и разобраться в чём именно беда.
