Domain Keys Identified Mail (DKIM) records allow you to digitally sign emails from your domain. Recipients of your emails can then verify that the message really did come from your domain and has not been tampered with.

DKIM works by using public and private encryption keys. The private key is used to create encrypted mail headers that are embedded in every email message you send. The public key is added to the DNS records for your domain which allows recipients to retrieve and then use it to decrypt the header and verify the message.

If you run your own mail server and would like to start signing your own emails, dkim.org will give you everything you need.

This guide will show you how to add a DKIM record to any domain name registered with LCN.

  1. Log in to your LCN account.
  2. Click the Domains icon and choose Manage.
  3. Click DNS Settings.
  4. Under the TXT Records section, Click ADD A TXT RECORD.
  5. In the Name field enter a string that will distinguish this key from any others, also known as a selector prefix, e.g. google._domainkey.
  6. In the Data field enter your public encryption key, e.g

  7. v=DKIM1; k=rsa;
    p=p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDeIhtCv3vUinyhKiKtZ8efjHGGo
