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@...  b@...  c@...  d@...
   e@... ...etc... aa@... ...etc...
