Er... if it's handling a reasonably high volume of mail. If it's only
churning out a message or two every ten minutes, I wouldn't bother; BIND
is a huge memory hog and also a program that tends to have to be
frequently upgraded due to security holes.
In other words, run a caching name server on your mail *servers*, but not
on every random Unix workstation that happens to be running qmail.
(Oh, and remember: If you have any programs that use the standard
gethostbyname() calls and you're using Solaris, link them directly against
libbind if you have a local name server. Otherwise, they'll still query
through nscd, which on versions of Solaris prior to 7 is single-threaded
for DNS queries.)
