relay
The address is a permanent alias at a forwarding service
Firefox Relay, SimpleLogin, Addy.io, DuckDuckGo Email Protection and their kind deliver to a real person's mailbox under a name they control; the identity is withheld, not the mailbox.

What it means
The relay list is read before the burner list, so a relay domain is never disposable: this weight of 5 replaces the disposable 80. The mailbox is probed like any other and domain_category answers relay.
It reads from is_relay, relay_service names the service, and it comes with no verdict reason.
What to do
Accept it. The owner can switch the alias off, which is a reason to stay worth reading rather than a reason to refuse.

}Abbreviated: a real answer carries all 46 fields, listed in the verify-email reference. The risk_signals entry shown is the one this signal adds; the weights of every entry in the list sum to risk_score.
