Enum MailExchangers 

pub enum MailExchangers {
    Hosts(Vec<String>),
    Null,
    Absent,
    Unknown,
}

The domain’s MX state as the posture lookup saw it.

Variants

Hosts(Vec<String>)

MX hosts (lowercase, no trailing dot), in preference order.

Null

A null MX (RFC 7505): the domain accepts no mail.

Absent

No MX records: mail falls back to the domain’s address (RFC 5321 §5.1).

Unknown

The MX lookup failed, so the state is not known.
