This article provides information on how to generate a 1024-bit DKIM key if your domain hosting is not allowing you to add the default 2048-bit DKIM key into the DNS.
You need to generate a 'short' 1024-bit DKIM key.
Note: Kerio Connect includes a 2048-bit DKIM public key. If the public key is too long (some providers may restrict the length of the TXT value), you can use an online DKIM key creator to create a 1024-bit key.
Follow these steps to generate a short DKIM key using the DKIM wizard:
- Go to the DKIM wizard page
- Enter your Domain name
- Click Create Keys
- Confirmation: The page displays your public and private keys. You may now add the new private key to Kerio Connect.
