With regexp substitution, this would give giving random users
control over destination host names, host addresses, and TCP ports.
Instead of using (regexp) to grab the nexthop from the recipient
localpart or domain part, specify the string explicitly.
/......(regexp)....../ ......$1......
/......whatever....../ ......whatever......
Repeat this for each such domain.
