Yes, that's what I did when I was doing mail things. There are a few reasons: reduce load on the shared central resolvers; reduce the latency of anti-spam blocklist lookups; better fate-sharing between the SMTP and DNS parts of the mail service. There's not much overlap between the kinds of queries done by mail servers and other DNS users, so there's limited benefit from sharing a single cache. There probably is benefit from sharing a DNS cache between multiple mail servers, but from my point of view it was easier to have one kind of machine that does SMTP + DNS than two different flavours of machine. (The admin effort is per flavour, not per server.) Tony. -- f.anthony.n.finch <d...@dotat.at> https://dotat.at/ Cape Wrath to Rattray Head including Orkney: Northeast 3 to 5 backing north 3 or 4.
