How to change outgoing mail server IP?

Sometimes, its handy to change the IP address that Exim uses. This can happen, when an IP address is either in a RBL or when you don't have a PTR for one of the IPs and you don't want to wait for the PTR to be setup on the other IP. Please follow the below step by step:

How to change the main EXIM IP:

• Login to the WHM (The login information is in your welcome email)
• Once logged in, on the left you will see a long list, scroll down until you see "Service Configuration"
• Then click on "Exim Configuration Editor", now we will need to edit the IP here.
• Search for the following line:

  ** Send outgoing mail from the ip that matches the domain name in /etc/mailips (*: IP can be added to the file to change the main outgoing interface)

• You will need to check the box, right next to it. Once that's done, scroll down to the bottom of the page, and click "Save Changes".

Modification from SSH [ADVANCED]:

Now, we will need to edit the "/etc/mailips" section, this will require SSH access, and a little bit of SSH knowledge. If your not sure, please don't do this, and ask for help from your web administrator or developer.

• Login using SSH (The SSH information is contained within your welcome email)
• Now, we will need to edit the /etc/mailips file.
• Once your editing this file with your favorite text editor (nano, vi, etc…), add the following line:

  *: Your-New-IP

• Please replace "Your-New-IP" with the IP address that you wish to use, you may use the second IP that you where provided with your VPS order.
• Now, please save the changes and restart EXIM.
• You may restart EXIM by doing: /etc/init.d/exim restart

Congratulations, you've successfully completed the EXIM IP change over!
