Ensim and SB nameservers

[Tazzman]

This in not so much a question about Ensim, I was just wondering what's the most effective way to combine Ensim with the DNS tool. I have installed Ensim pro myself on a plain Redhat server here and the primary nameserver is running on the server under the same name as the server (as Ensim sets it up like that standard and it suits me).

I've currently set all my sites up using the SB nameservers as slaves, but is this the best solution? Is it maybe better to set the SB nameservers as master?

ServerBeach nameservers can do:

1. Master and Slave
2. Slave only

With option 1, you will use ns1.geodns.net and ns2.geodns.net as the nameservers for your domains. You need to log into MyServerBeach and use the DNS Tool each time you want to make a change to your zones. The biggest advantage to this is you don't need to worry about making sure your nameservers are functioning properly. The DNS Tools also keeps you from making some minor mistakes, though it is still possible to mess things up :)

Option 2 allows a little more flexibility than Option 1, and also increases your redundancy. You still need to add the domain in the DNS Tool, but you do all zone maintenance on your own server. Once the zone is updated on your server, our servers are notified and download the new information. This is useful if you tend to make a lot of changes to a lot of domains and feel more comfortable using the control panel or have your own way to make changes quickly.

The other option is to do master and slave on your own server, but this defeats the purpose of having two nameservers .. you have zero redundancy. If something is misconfigured or the DNS service crashes, your domains are dead. A lot of virtualhosters like this option because they may have thousands of domains and could be making a hundred changes per day, and it would be very difficult and time-consuming to do this with the DNS Tool.

Does the reverse DNS entries for MX records set by default or I have to submit my request to add it in? I use SB nameservers as my master/primary ns. However, I am having problem to receive an external email. Even the messages were successfully receiced, they were delayed over 3-4 hours. Is it because of the reverse DNS entries for MX records that didn't exist, or my sendmail server configuration problem? I didn't make any changes on the sendmail. Everything is original setting. I only added my IP, domain, sub-domain and MX record to SB nameserver throught DNS Tools. Do you have any idea about my problem? Thanks.

The reverse (PTR) entry for your primary IP address is automatically set to the hostname of your server. If you are using a different IP address for your MX record, you will need to request to have the PTR entry changed. Also make sure that your MX record points to a hostname which is defined by an A record, not a CNAME. CNAME records require an extra step to resolve and some mail servers will refuse to send mail to a CNAME. If everything I mentioned is set properly, you may want to have someone look at your mail logs and mail configuration.

Thanks for you reply. However, I only have 1 domain name on my server and is using the original ip that was given by SB. Should I assume that the reverse PTR had been added? I did nslookup my ip address, and I got Non-existent domain. If the reverse PTR was automaticlly set, nslookup should get my domain. Is it someting wrong on my domain/ip setup on SB DNS server?
