How to enable DKIM in DirectAdmin?
DKIM should be enabled by default on new domains, but if you find your domain does not have a DKIM record in DNS, you can easily enable DKIM for your email in DirectAdmin by doing the following:
Go to the E-Mail Manager menu item and choose E-mail Accounts
Click the ENABLE DKIM button
That's it! Your domains will now have a TXT record in DNS for DKIM!
