DKIM - Domain Keys Identified Mail

Domain Keys Identified Mail (short: DKIM) can help recipients determine whether an e-mail is legimate, just like SPF and Sender ID. The biggest difference is, that DKIM uses cryptography to prove legitimacy. In DKIM a digital key is placed in the domain. The sender has another (secret) version of this key, and uses it to calculate a digital signature for the e-mail. The key in the domain can be used to verify whether the signature is legimate.

Having a DKIM Signature on your e-mail will significantly improve your chances on being delivered in to the inbox. Our system checks whether you have a DKIM signature, and if it is valid. Our premium reports offer detailed information on your signatures.
