Enum Flag 

pub enum Flag {
    Feedback,
    FeedHere,
    Exploded,
    Unknown(String),
}

A value of the f= tag of a DKIM2-Signature (§10.10). Flag names are case-sensitive.

Variants

Feedback

feedback: the signer requests feedback about how the message is handled.

FeedHere

feedhere: feedback should be relayed through this hop instead of being sent directly to the requestor.

Exploded

exploded: the signer is sending this message to more than one recipient (§12.5). Not allowed on the first signature (i=1).

Unknown(String)

Any other flag, kept verbatim. Unknown flags have no effect.
