Change Mail Server IP

Sometimes your server’s IP address may get black listed by most of RBLs. In such situation a quick solution is to route the emails through a secondary IP address on the same server which is not black listed. There are two options to switch the mail server IP.

1. In Cpanel:

Login to WHM

Click Exim Configuration Editor

Check the box next to:
“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)”

Save Changes

Then edit the file /etc/mailips
vi /etc/mailips

and add:

*: newIP

Restart exim

or

2. Through Shell

vi /etc/exim.conf

Locate remote_smtp

Change as per below:

remote_smtp:

driver = smtp

#interface = ${if exists {/etc/mailips}{${lookup{$sender_address_domain}lsearch{/etc/mailips}{$value}{}}}{}}
#helo_data = ${if exists {/etc/mailhelo}{${lookup{$sender_address_domain}lsearch{/etc/mailhelo}{$value}{$primary_hostname}}}{$primary_ho stname}}

interface = 111.222.333.444 # Change to your server IP address.

Save changes and exit.

Restart Exim

  1. Thanks!

    Be careful with the 2nd method though… Aren’t direct changes to exim.conf going to be overwritten with cPanel upgrades?
