Enum TlsAttemptOutcome 

pub enum TlsAttemptOutcome {
    Success {
        policy: &'static str,
    },
    NotAdvertised,
    Rejected {
        code: u16,
        message: String,
    },
    HandshakeFailed(TlsOutcome),
}

Outcome of one STARTTLS attempt, carried by DeliveryEvent::TlsAttempt. The four variants discriminate between TLS success, server-side refusal (still safely usable in plain), and handshake failure (with the structured mailrs_smtp_client::TlsOutcome underneath).

Variants

Success

STARTTLS completed; encrypted channel established. policy tells the report which policy gated this attempt ("dane", "sts", or "opportunistic").

Fields

policy: &'static str

Which policy class was active for this attempt.

NotAdvertised

Server did not advertise STARTTLS in the EHLO response. Maps to RFC 8460 starttls-not-supported.

Rejected

Server rejected the STARTTLS command (returned 4xx/5xx).

Fields

code: u16

SMTP response code.

message: String

SMTP response text.

HandshakeFailed(TlsOutcome)

TLS handshake started but failed mid-way. The wrapped mailrs_smtp_client::TlsOutcome is RFC 8460 §4.3-aligned.
