Enum ChainBinding 

pub enum ChainBinding {
    Envelope {
        mail_from: String,
        rcpt_to: Vec<String>,
    },
    NextDomain(String),
}

How a DKIM2-Signature links to the next hop in the chain of custody (§10.5 to §10.7, §12.2 and §12.3).

Variants

Envelope

The SMTP envelope used when the signer sent the message (mf= and rt=). Addresses are RFC 5321 paths including the angle brackets; mail_from is <> for a null reverse-path.

Fields

mail_from: String

mf=: the MAIL FROM reverse-path.

rcpt_to: Vec<String>

rt=: the RCPT TO forward-paths.

NextDomain(String)

nd=: domain of the next DKIM2-Signature, used for an imaginary hop where the message changes domain without an SMTP transaction.
