If you're going to be sending both web and email traffic to your KH's server, why not just use the nameservers? That'll point web, email, ftp, and everything.
It resolved to KH for me and I see no issues with your DNS configuration. Most likely the DNS resolvers your client machine is using are caching or your local machine is caching. I would try clearing your local DNS cache and see if that helps.Ok I have moved the server DNS records to point to my Knownhost DNS records - now my site is not responding - it seems to be ok on global DNS propagation just not resolving for me!
