Domain Keys Identified Mail (DKIM) is designed to make it difficult for criminals to steal the identities of legitimate organizations. This authentication technology allows senders to “sign” a message to prove it really did come from them. Once DKIM signing has been enabled for a domain, all outbound email messages from that domain will be signed using the current DKIM key.
To enable DKIM:
- Go to HostPilot® Control Panel > Services > Email Protection > Settings > Digital Signature (DKIM).
- Choose the domain you would like to configure DKIM for and click on Generate keys.
- You can now see the values for creating a new TXT record for your domain. Contact your DNS provider to add a new TXT record.
Important: update the TXT record before clicking Enable digital signing, otherwise it might result in non-delivery of messages to the recipient depending on the recipient's mail filter configuration.
Here is what this TXT record should look like:
Host Name: 2017071012342006._new.yourdomain.com
Note: if Intermedia hosts DNS records for the domain, the corresponding TXT record will be created or removed automatically.
Once the TXT record is updated, go back to HostPilot > Services > Email Protection > Settings > Digital Signature (DKIM) > Enable digital signing.
To disable DKIM select the domain for which the DKIM is enabled and in the new menu, click Disable digital signing:
Important: remove the TXT record after clicking Disable digital signing.
To create a new DKIM key:
- Go to HostPilot > Services > Email Protection > Settings > Digital Signature (DKIM).
- Check settings for the domain with enabled DKIM.
- Click Generate new keys
- Click Switch to key
Important: update the TXT record simultaneously with adding a new DKIM key or create the second TXT record with a new DKIM key before clicking Switch to key, otherwise it might result in non-delivery of messages to the recipient depending on the recipient's mail filter configuration.
