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. 

Enabling DKIM

To enable DKIM:

  1. Go to HostPilotĀ® Control Panel > Services > Email Protection > Settings > Digital Signature (DKIM).
    DKIM
  2. Choose the domain you would like to configure DKIM for and click on Generate keys.
    DKIM
  3. 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.
    DKIM

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

Text: v=DKIM1;t=s;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCZUKB+qpyR6TJsA8yjNBEpb7
CFeak2iwEUNlNgJuj3ncKfm+2we7B8GahlKn+LBx4d0ufXwv9gQQ/ALpHidMoVXCIv7Ms+YbGcifAdCtomIFqt
ByaIASiNApvJmqN4T3GIzJbWckqaKbHDXMLddGA8LrtJTMIVganEGOeZtt9hjQIDAQAB

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.

Disabling DKIM

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.

Generating new DKIM key

To create a new DKIM key:

  1. Go to HostPilot > Services > Email Protection > Settings > Digital Signature (DKIM).
  2. Check settings for the domain with enabled DKIM.
    DKIM
  3. Click Generate new keys
  4. Click Switch to key
    DKIM

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.
