disposable
The domain belongs to a disposable, temporary email provider
The domain, or the mail infrastructure behind its MX hosts, is on the open disposable-provider list. The inbox exists for minutes or hours.

What it means
Spaw syncs the open disposable-provider list weekly and extends it with local overrides, and it also matches the operators behind a domain's MX hosts, so a fresh burner domain on a known disposable backend is caught before the list catches up. Whoever signed up with a disposable address does not expect to hear from you again.
Disposable domains are never sent to the mailbox probe, so smtp_checked is false. The risk weight of 80 puts the address in the high band by itself.
What to do
For signups, block the address or ask for a different one. For existing lists, do not send: even when the message is accepted nobody reads it, and these domains attract spam-trap conversions.
