Jesli jeszcze tego nie zrobiliscie, to zapatchujcie sendmaila. Okolice
linijki 316 w daemon.c powinny wygladac nastepujaco:

           t = accept(DaemonSocket,
                (struct sockaddr *)&RealHostAddr, &lotherend);
            if (t >= 0 || (errno != EINTR && errno != ENETUNREACH &&
                            errno != EHOSTUNREACH))
                break;
