# `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.

- Weight: +5
- Dataset: forwarding-services
- Read from: `is_relay`
- Verdict reasons it comes with: none — a score-only signal

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.
