Not bind. djbdns. http://cr.yp.to/djbdns.html
It makes a huge performance difference. Also, your hoster may not like
it if you use their DNS for such a big mailinglist.

What QMQP does is move the point where the bandwidth is consumed. For
personalized messages, QMQP has little to no benefit.
You could use QMQP to distribute the load over several qmqp servers,
but you would have to set up these qmqp servers yourself.
Note that RAID has *very* little benefit to a qmail server. Much
better would be (IMHO) to run a qmail queue on each disk, and
distribute your mail over those.
