I'm running sendmail on my 5.2.1 system, and have a number of DNSBLs set up in my sendmail configuration. I am not currently running BIND (or any other nameserver), and therefore have configured my system to use one of my ISP's DNS servers.

I've noticed that each attempted connection to my mail server now generates a flurry of DNS requests from my mail server to my ISP's DNS server.

I'd like to streamline this process, but I don't really want to take on DNS administration. I've heard about caching DNS servers, and "tiny DNS", and I wondered if they might suit my needs.

As with bind, setting up tinyDNS's dnscache program is pretty trivial. See the instructions here: http://cr.yp.to/djbdns.html (He even has different HOWTOs for the different usage scenerios)

Note one thing: if you install tinyDNS from ports, your svscan directory will
be /var/service instead of /service to comply with hier(7).  Adjust the
instructions accordingly.
