We switched from bind to unbound for our mailer's and content filter's DNS server a couple of months ago, I think it was as good choice: lean, mean and designed from grounds up with standards, security, speed, low footprint and DNSSEC in mind. (I even run unbound on a laptop natively under Win7 as its only resolver/server :) Mark
