Remove Exim Connection limits for specific IP addresses

Introduction

In some instances, you may need to increase or remove limits entirely for Exim connections from a specific host or set of hosts. The steps outlined below will allow you to do so.

Procedure

1. From SSH create a file within /etc of your choosing; As an example please see the below file:

[root@testing ~]# cat /etc/exim_max_connections_per_host
#default
0.0.0.0/0 4

#localhost
127.0.0.1 40

#Your IP Address
1.2.3.4 0
[root@testing ~]#

Note - you would use 0 to indicate No limit.

2. From WHM access the Exim Configuration Advanced Editor

3. Add a new option by scrolling to the "Add additional configuration setting" button:

4. Scroll to the bottom of the Editor interface and click "Save"

Once completed the new Exim configuration will be applied and your IPs show no longer be limited.
