I agree, but one of the more vocal Postfix users does not. Perhaps we can ignore him as an unrepresentative zealot. Objectively, I see no reason to say no to a local validating cache. If RedHat can standardize on a local validating cache on every machine, that *is* better than hacking the AD bit, provided you can ignore the zealots who insist that with a few LAN-local caches, adding local caches on each machine is somehow bad. My point that with virtual machines context switching to a different VM is likely much more expensive than context switching to a local process did not make much of an impression. So *if* there is a local resolver and it is the only one used, great! No need to disable the AD bit. If there is not, perhaps "failing safe" is sensible. It may be enough to design systems that default to local resolvers, and users who change that are free to shoot themselves in both feet. -- Viktor.
