Zapnel did not allow you to create TXT record with more than 100 charecter. So you can’t create DKIM in Zpanel. Don’t worry I have a idea. You can create DKIM in zpanel using following meathod.
Create a small TXT entry in DNS for examle.com (Say you want to set DKIM for examle.com)
1st : login to phpmyadmin with root user
2 : select database zpanel_core,
– select table x_dns,
– click in the menu “Structure”,
– click in “Edit” for column dn_target_vc,
– change “Length/Values” from 100 to 1000.
Now search for the TXT record you have created (Small TXT Entry) edit as per dkim record.
Database part is done.
3 :Go to /etc/zpanel/configs/bind/zones
Open the file examle.com.txt
and serch for the TXT entry and edit accordingly. Now it is done. Just rboot your server.
Check DKIM is working or not by send a email.
