How to register a domain with using extra IPS

//  Let's get started with following simple steps  // :-

1. >

       Login to your registrar panel (Godaddy, Enom, etc..).

2. > 

      Select the domain you want to use & find where you can 'Register New DNS'

3. >

      Put in ns1.yourdomain.com and ns2.yourdomain.com in the respective fields.

4. >

      Put in the IP addresses < either yours or the ones provided to you by your host >

5. >

      Hit the save or submit button.

    ** NOTE:- If you are a regular reseller the rest is done by your host on their end so notify them that you            .         have done your part, If you run a dedicated server, read on.

6. >

      Login to your WHM panel as "root",

7. >

      Go to 'Reseller Center', select 'mydomain.com'. Click on the 'Edit Domains/Privilages' icon.

8. >

      When the page loads scroll down & put in the new nameservers, in this case ns1.mydomain.com &  

          ns2.mydomain.com.

9. >

       Save them & scroll down to 'DNS Function' and select 'Edit DNS Zone'.

10. >

      You will notice that the new nameservers are now located in the top 2 text fields Scroll all the way down 

          to where it says 'Add new A entries'.

11. > 

        In the first text field put in the nameserver & in the second empty text field put in the IP address. So it 

          will look something like this:-

          ns1.mydomain.com 14400 IN A 1.1.1.1

          ns2.mydomain.com 14400 IN A 1.1.1.2

12.  > 

         Click Save & you are done Enjoy.

Properly Rejected Invalid Emails

//**Just read the method given below to resolve this issue**//  :--

*******************************

Mail queue fill up with bounce messages to non-existant spammer email addresses, By default. If an email comes into your server addressed to an invalid recipient, Exim will accept the message from the delivering agent, and then generate a return email to them explaining that the address is invalid, With this little tweak, you can make exim tell the delivering agent,Tthat address is invalid at the time the message is being delivered.

Method 1)

. Open WHM and click on Exim Configuration Editor

. Click on the Switch to Advanced Mode button.

. Scroll down until you see the section on ACL's. You'll see three boxes. In the middle box, locate the section that reads - See Section A:

--------------------------------------------------------------------------------------------

Method 2) Recommended

. Login into SSH and su to root.

. pico /etc/exim.conf

. Ctrl + W and type in: accept  domains , Notice the two spaces. Look for something like this below.

Section A :-

accept  domains = +local_domains

accept  domains = +relay_domains

accept  hosts = +relay_hosts

accept  condition = ${perl{checkrelayhost}{$sender_host_address}}

Between

accept domains = +local_domains

&

accept domains = +relay_domains

add the following:

endpass

message = unknown user

verify = recipient

Make sure each line lines upYou might need to add two spaces before each line, The final section will look like this :-

accept domains = +local_domains

endpass

message = unknown user

verify = recipient

accept domains = +relay_domains

accept hosts = +relay_hosts

accept condition = ${perl{checkrelayhost}{$sender_host_address}}

Scroll all the way to the bottom and click on Save.
