been used to locate the Gatekeeper. Depending on which was used, the received URI could be
in one of three forms:
user@10.0.0.1
user@srv.record.domain.name
user@a.record.domain.name
Each of these should be able to discover an endpoint registered as either user or
user@a.record.domain.name.
On receipt of the URI the Gatekeeper will modify the URI by removing the @ and host if the host

The Gatekeeper will then search for registrations which match either the modified URI, or the
modified URI with the LocalDomain DomainName appended.
