gnus: Scoring On Other Headers

 
 7.9 Scoring On Other Headers
 ============================
 
 Gnus is quite fast when scoring the “traditional” headers—‘From’,
 ‘Subject’ and so on.  However, scoring other headers requires writing a
 ‘head’ scoring rule, which means that Gnus has to request every single
 article from the back end to find matches.  This takes a long time in
 big groups.
 
    You can inhibit this slow scoring on headers or body by setting the
 variable ‘gnus-inhibit-slow-scoring’.  If ‘gnus-inhibit-slow-scoring’ is
 regexp, slow scoring is inhibited if the group matches the regexp.  If
 it is ‘t’, slow scoring on it is inhibited for all groups.
 
    Now, there’s not much you can do about the slowness for news groups,
 but for mail groups, you have greater control.  In To From
 Newsgroups, it’s explained in greater detail what this mechanism does,
 but here’s a cookbook example for ‘nnml’ on how to allow scoring on the
 ‘To’ and ‘Cc’ headers.
 
    Put the following in your ‘~/.gnus.el’ file.
 
      (setq gnus-extra-headers '(To Cc Newsgroups Keywords)
            nnmail-extra-headers gnus-extra-headers)
 
    Restart Gnus and rebuild your ‘nnml’ overview files with the ‘M-x
 nnml-generate-nov-databases’ command.  This will take a long time if you
 have much mail.
 
    Now you can score on ‘To’ and ‘Cc’ as “extra headers” like so: ‘I e s
 p To RET <your name> RET’.
 
    See?  Simple.
