Domain and E-mail Verification with Google Apps

For domain owners using Google Apps

Learn how to verify your domain with a TXT record or your add e-mail authentication by implementing the DKIM authentication method.

You can verify your domain by adding a digital signature. This confirms that you are the owner of the domain. Additionally, with the DomainKeys Identified Mail (DKIM) process, your outgoing e-mails are signed using a private and public key. This allows the recipient's mail server to determine whether the e-mail really came from the sender address or if it has been forged.
