Abstract
The DomainKeys Identified Mail (DKIM) protocol applies a domain-level cryptographic signature to an e-mail message. DKIM only guarantees authenticity of the message content and does not consider the message envelope. This allows for replay attacks by recycling a signed message with an arbitrary new set of recipients. This document presents a protocol extension that can include original envelope information in the signature data, so that an altered that information renders the signature invalid.
