Add Relay to Exim: How?

Large amounts of email can be transmitted over as the mail relay routes messages through a reliable third party. In contrast to a self-managed server, the majority of mail relay services come with a tidy, appealing user interface (UI). Hence the mail relay is a desirable software among users.

Today, we will see the steps to set up mail relay on Exim ISP Manager Panel and Exim Mail Server.

How To Add Relay to Exim Mail Server?

While installing Exim on a CentOS host using the yum package manager, it is important to enable mailserver IP relaying through smarthost. Find the line referred to below in the configuration at /etc/exim/exim.conf, open it and add the relay server IP 109.201.130.65 at the end as shown below.

hostlist   relay_from_hosts = 127.0.0.1

eg: hostlist   relay_from_hosts = 127.0.0.1 : 109.201.130.65

Then instruct Exim to stop listening for incoming mail exclusively on the localhost address, which is the default. Once more, locate the configuration line below and add a hash (#) in front of it to comment it out.

local_interfaces = <; 127.0.0.1 ; ::1

eg: #local_interfaces = <; 127.0.0.1 ; ::1

In exim.conf, remove the comment and modify the smarthost section as follows:

smarthost:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
route_list = * 109.201.130.65
no_more
no_verify

Finally, save the modified config file and restart Exim on this server. Now the setup of mail relay on exim is complete.

How To Add Relay to Exim ISP Manager Panel?

We must make two configuration adjustments while installing Exim on a CentOS host using the yum package manager. The first step is to enable mailserver IP relaying through smarthost. Find the line referred to below in the configuration at /etc/exim/exim.conf, open it, and add the relay server IP 109.201.130.65 at the end as shown below.

hostlist   relay_from_hosts = 127.0.0.1

eg: hostlist   relay_from_hosts = 127.0.0.1 : 109.201.130.65

Then, below the “begin routers” line in exim.conf, uncomment and update the smarthost section as follows:

smarthost:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
route_list = * 109.201.130.65
no_more
no_verify

Restart Exim on this server after saving the changed configuration file. The setup is all done now.
