UNKNOWN_AUTHSERV_ID =

RFC 8601 §2.2 requires an authserv-id. Without one we say so out loud rather than emitting a header that appears to be signed by nobody.

NO_RESULTS =

TOKEN =

A pvalue may be an RFC 2045 token or a bare addr-spec, so "@" and "." ride along unquoted; everything else has to become a quoted-string.

Constructor Details

#initialize(spf:, dkim:, dmarc:, arc: nil, mta: nil, header_from: nil) ⇒ AuthenticationResults

header_from is optional: a DmarcResult carries a verdict, not an identity; pass the From: domain to have it reported as header.from.

#to_s ⇒ Object

The value alone — everything after "Authentication-Results:" — so the caller writes the field name itself.
