Displaying stuff from spamassassin headers in the summary buffer?

Displaying stuff from spamassassin headers in the summary buffer?

[Steinar Bang]

Is it possible to display something interesting extracted from
spamassassin headers in the summary buffer?

Here's an example:
X-Spam-Checker-Version: SpamAssassin 4.0.0 (2022-12-13) on schwantz
X-Spam-Level: **
X-Spam-Status: No, score=3.0 required=5.0 tests=AC_BR_BONANZA,
	DKIM_ADSP_CUSTOM_MED,FORGED_GMAIL_RCVD,FREEMAIL_FROM,HTML_MESSAGE,
	T_KAM_HTML_FONT_INVALID,T_SCC_BODY_TEXT_LINE,URIBL_ABUSE_SURBL,
	URIBL_BLOCKED autolearn=no autolearn_force=no version=4.0.0

I dunno what "interesting" would mean here, but at least the spam score
in some form.

Right now I have to do C-u g to see these headers in the raw message.

t runs the command gnus-summary-toggle-header (found in
gnus-summary-mode-map), which is an interactive byte-compiled Lisp
function in ‘gnus-sum.el’.

It is bound to t and W t.

(gnus-summary-toggle-header &optional ARG)

Show the headers if they are hidden, or hide them if they are shown.
If ARG is a positive number, show the entire header.
If ARG is a negative number, hide the unwanted header lines.

When you say this, I think I actually knew this and had forgotten
it... I wonder of how I landed on 'C-u g'?

Maybe I was told the previous time I asked this quesetion? (I miss
gmane's xapien search from 'G G'...)

But anyway: what I really-really-want is to have spam-tagged articles be
flagged, highlighted some way in the summary buffer by the spam score.

I think the concensus the last time I was "no" since the spamassassin
headers weren't in the set cached for use in the summary buffer, so the
entire article must be loaded and parsed.

But things may have changed...?

Thanks!

There's also `gnus-visible-headers', if you want to always see the
result in the article buffer.

I believe you could add your desired header to the `gnus-extra-headers'
variable, and get it from there?

Yes... but I think the 't' trick further up in the thread is sufficient
to me here.

Thanks! I will investigate and follow up in this thread with what I find out.

Here are some old settings that I'm not using these days, but which
might do things similar to what you want:

(add-to-list 'nnmail-extra-headers 'X-Spam-Status)
(add-to-list 'gnus-extra-headers 'X-Spam-Status)

(defun jdc-spam-status (h)
  "The spam rating from the X-Spam-Status header."
  (string-to-number (gnus-replace-in-string
		     (gnus-extra-header 'X-Spam-Status h)
		     ".*hits=" "")))

(defun gnus-user-format-function-s (h)
  (let ((ss (jdc-spam-status h)))
    (if (> (abs ss) 10)
	(round ss)
      ss)))

With the above settings, I'm able to display the spam score in the
summary buffer line using "%us" in gnus-summary-line-format.  This could
be adapted to display other info.

I also sort my spam group by spam score, so the ones that at most likely
to be mis-classified messages are together:

(defun jdc-gnus-article-sort-by-spam-status (h1 h2)
  "Sort articles by score from the X-Spam-Status: header."
  (< (jdc-spam-status h1) (jdc-spam-status h2)))

(defun jdc-gnus-thread-sort-by-spam-status (t1 t2)
  "Sort threads by score from the X-Spam-Status: header."
  (jdc-gnus-article-sort-by-spam-status
   (gnus-thread-header t1)
   (gnus-thread-header t2)))

But I don't see where I enable these functions.

These are the remaining puzzle pieces I was too lazy to look up! Thank you.
