I've just started learning about linux systems, mail servers, and non-helpdesk IT stuff two months ago so you may have to dumb down some replies =P I'm working on a centos server that has postfix and we need to get DKIM up on it to verify our outbound emails. I'm using http://www.howtoforge.com/set-up-dkim-on-postfix-with-dkim-milter-centos-5.2 as reference, however i'm confused about the part where it talks about DNS and zone files. From what I've gathered, I need something called BIND (i'm not sure if that exists on this server) which creates the directory /var/named that contains the zone file? I don't see that on my server... My main question(s) are where is the zone file, (or if i don't have it) which package do I need to install to get it? Thanks for any insight
The first question is if you host the zone file for the domain, or if someone else is running the authoritative nameservers for your domain - you can find that out by running Code: dig ns yourdomain.com
