If the variable
nil, the NNTP
server name followed by the user login name is used in the `Path:'
field of article headers you post. If it is a string, the string
followed by the user login name is used instead. Otherwise, if it is
nil, only the user login name is used. This is called the
GENERICPATH feature in the Bnews system.
For example, to define the generic path `flab', put the following codes in `.emacs', `site-init.el' or `default.el'. If you are a system administrator and are installing GNUS for other users, `site-init.el' is the best place to define it because the definition is common to all users of the system having the same domain and organization (see section Domain and Organization).
(setq gnus-use-generic-path "flab")
In this case, the `Path:' field will be generated as `Path: flab!user'.
