No, no, you had a point: even Solaris 2.x (a recent OS), has a file
descriptor limit set by default at 64. The number of file descriptors
needed by qmail is 2*concurrencyremote+5 (this is due to the fact that all
fds to qmail-remote's are kept open,...).
So for a reasonable concurrencyremote (>30), you will need to increase the
fd limit. But even if you do, you *can't* bring concurrencyremote over 256.
