Sendmail x.x.x DoS
------------------

Take a look at this piece of code (src/daemon.c):

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


Err, yeah. When I fixed that bug, I used:

                        if (t >= 0 || (errno != EINTR && errno != ENETUNREACH &&
 errno != EHOSTUNREACH))

That cured the intermittent unavailability which I was experiencing (due to
lusers, not Skript |<iddies).
