The archive removes the domain, so for example, my address appears
as jgh at ... It would take a lot of surplus computing power to bash
away generating every combination of /domain/ name to tag a user
name onto. The usual method is to discover a domain name, and then
bash away prefixing it with programatically generated user names,
eg:
   a at domain.name  b at domain.name  c at domain.name  d at domain.name
   e at domain.name ...etc... aa at domain.name ...etc...
