// rather than a remote receipt: with MtaRoute + MtaOutboundStrategy in place the
// recipient is accepted and queued to the tor-smtp relay, whereas an unrouted
// .onion domain has no MX and returns a delivery failure to the sender. The
// recipient domain is deliberately not a local domain — is_local_domain wins over
// the .onion match in the strategy, so a self-addressed onion would route 'local'
