And it also seems that postfix doesn't use nscd, although a simple
config change solves that; other apps also do not use nscd and they
can't be made to use it, apparently. Thus disabling nscd and using
dnsmasq as I do means that all queries would go to dnsmasq and the
global hit ratio should increase.

That assumes that dnsmasq does not also have some built in way to go
around it. (I really don't know).

There comes a point, especially in things like spamassassin that use
DNS hits to evaluate spam hashes, where adding stuff to the cache is
counter productive.

Somewhat OT, but spamassassin does not use the libc resolver, it does
it's own asynchronous dns lookups.
