Initial match-all rule

The special pattern  is applied before any other rewriting,  and matches all addresses. Its usual use is as a fundamental part of a "direct LDAP" setup, to achieve LDAP-based routing of domains. That is, its usual use is in conjunction with a template looking up domains in LDAP, so that domains are looked up in LDAP prior to any other rewriting. For example: $&#x2a;  $A$E$F$U%$H$V$H@official-host-name-of-l-channel
