Sometimes we may need to bypass the SMTP authentication for the certain sender’s IP address.
In order to do so in Directadmin server, we’ll need to add sender’s IP address into exim.conf:
Find the line below:
hostlist relay_hosts = net-lsearch;/etc/virtual/pophosts
Add senders IP address:
hostlist relay_hosts = net-lsearch;/etc/virtual/pophosts : xx.xx.xx.xx
Where xx.xx.xx.xx is senders IP address
Once done, restart exim service
In cPanel, we just need to add sender’s IP to the following file:
[cc]/etc/alwaysrelay[/cc]
Once done, restart exim service
