Why You Need DKIM Enabled on Your Domain?
DKIM helps prevent email spoofing. Firstly let us define the email spoofing in some words: it is when spammers forge the sending address. Therefore to look like your own email.
For instance, spammers spoof your address to make it more likely that recipients will open spam emails. As a result less likely that messages will be marked as spam. Consequently and more difficult to find the true spam source.
To reduce the number of failed delivery notifications that you receive when spammers forge messages from your domain. Just activate the DKIM and SPF. So they work to prevent spammers from forging messages that claim to be from your domain.
How to Generate DKIM and SPF in cPanel account

- From Email Deliverability Page: Under DKIM If not generated you will see install button.
