5.6.3.  The tail-entry

   For historical reasons, the tail-entry (i.e. the rightmost entry in
   the Path-content) is regarded as a "user name", and therefore MUST
   NOT be interpreted as a site through which the article has already
   passed. Moreover, the Path-content as a whole is not an email address
   and MUST NOT be used to contact the poster. Posting and/or injecting
   agents MAY place any string here.  When it is not an actual user
   name, the string "not-for-mail" is often used.

   Often this field will be the only entry in the region (known as the
   pre-injection region) after the '%', although there may be entries
   corresponding to machines traversed between the posting agent and the
   injecting agent proper. In particular, injecting agents that receive
   articles from many sources MAY include information to establish the
   circumstances of the injection such as the identity of the source
   machine (especially if an Injector-Info-header (6.19) is not being
   provided). Any such inclusion SHOULD NOT conflict with any genuine
   site identifier. The '!'  path-delimiter may be used freely within
   the pre-injection region, although '/' and '?' are also appropriate
   if used correctly.
