Implementing DKIM on a Domain

More information about DKIM can be found here.

1. To enable DKIM signing, make sure you are in the "Domains" section and click the "Actions -> Edit" button for the selected domain.  
2. On the next screen, click "DKIM -> Enable".
3. If you have your own keys, fill in the form below. To generate keys, click on "generate DKIM".       
4. The system will generate everything you need.
5. The public key must be included into the DNS records of this domain. It is necessary to create a DNS record for:

"selector._domainkey.yourdomain.cz"

"v=DKIM1; k=rsa; p=public_key"

6. Selector is the value specified when entering the key. 7. You can verify the correctness of settings using the commands:
Linux:

host -t TXT selector._domainkey.yourdomain.com

Windows:

nslookup -type=TXT selector._domainkey.yourdomain.com

8. The output should look like this. The "p=" part should correspond to the public key from the entry.
