You can certainly run a caching nameserver - this is actually quite a polite thing to do - the more you cache, the less you send out to the 'Net. I use BIND for this, and the config is pretty straight forward. Others use djbdns, but I never got on with it. See which you prefer. Following on from that, no, you won't run any primary or slave zones. ZoneEdit's servers will answer requests for your mail server's address when another mail server has something to deliver. My ZoneEdit account specifies that mail for my domain is directed to my host - there is no need to specify more then this to handle incoming mail. For outgoing mail, you can either use your ISP's resolvers, or, if you set up a caching name server, set your primary resolver to 127.0.0.1. The config for your resolver will then have settings for upstream resolvers to query - usually your ISP's, again. Sendmail (and any other app that needs name resolution services) will then use the right resolvers, based on what they find in /etc/resolv.conf I hope I am closer to the mark this time! ;-) Dan > Like I mentioned earlier, I would understand if this is asking too much > in one post, but I'd appreciate someone who might have been in the same > situation to give me some pointers / guidance on this one. > > Thanks for taking the time to respond, Dan. > > Stacey > > -- Daniel Bye PGP Key: ftp://ftp.slightlystrange.org/pgpkey/dan.asc PGP Key fingerprint: 3D73 AF47 D448 C5CA 88B4 0DCF 849C 1C33 3C48 2CDC _ ASCII ribbon campaign ( ) - against HTML, vCards and X - proprietary attachments in e-mail / \ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
