Header Fields and Split Fancy

Header Fields and Split Fancy

[Holger Sparr]

Hi,

I tried to set up nnmail-split-fancy. I encountered a problem caused
by the capitals in the header fields of my messages.

In the variable `nnmail-split-abbrev-alist' all of the field names
start with a down-case character. I tried to add regular expressions in
the same manner which include the capitalized field names like this.

,----
|  (add-to-list nnmail-split-abbrev-alist 
|              '((anyuc ."From\\|To\\|Cc\\|Sender\\|Newsgroup")
|                (mailuc . "Mailer-daemon\\|Postmaster\\|Uucp")
|                (touc . "To\\|Cc\\|Apparently-To\\|Resent-To\\|Resent-Cc")
|                (fromuc . "From\\|Sender\\|Resent-From"))
|              :group 'nnmail-split
|              :type '(repeat (cons :format "%v" symbol regexp)))
`----

but did not succeed. Neither I did receive an error message nor Gnus
was adding the changes.

What do I miss here? 

Is it possible to "wash" the headers as assumed by nnmail-split-fancy?

TIA,

Holger

Did you really see a problem with these abbrevs, ie did you see wrong
splitting because of header case?

If so, then Gnus should set case-fold-search to t while matching the
header names.

Right now, I am using this for splitting:

	("From"	".*elsevier"			"mail.elsevier")
        [...]
	("To"	"sparr@\\|Sparr@"		"mail.other")
	("Cc"	"sparr@\\|Sparr@"		"mail.other")
	("To"	"sparr+usenet@"
	    (| ("subject"	"Re:.*"		"mail.answer")
	       ("references"	".*@.*"		"mail.answer")
	       "mail.spam"))
	"mail.spam")

Without being case sensitive like:

	(from	".*elsevier"			"mail.elsevier")
        [...]
	(to	"sparr@\\|Sparr@"		"mail.other")
	(to	"sparr+usenet@"
	    (| ("subject"	"Re:.*"		"mail.answer")
	       ("references"	".*@.*"		"mail.answer")
	       "mail.spam"))
	"mail.spam")

the incoming messages went to "spam".

I think, using these abbrevs looks nicer. I just wanted to keep these
additional abbrevs in the right place. 
I am curious about what was wrong in my (add-to-list...) formulation.


Thanks for your time.

Can you try to create a small, self-contained "nnmail-split-fancy"
where you can reproduce the problem?

Delete the `:group' and `:type' clauses:

(add-to-list nnmail-split-abbrev-alist 
             '((anyuc ."From\\|To\\|Cc\\|Sender\\|Newsgroup")
               (mailuc . "Mailer-daemon\\|Postmaster\\|Uucp")
               (touc . "To\\|Cc\\|Apparently-To\\|Resent-To\\|Resent-Cc")
               (fromuc . "From\\|Sender\\|Resent-From")))

I did that before and got:

         Wrong type argument: symbolp, ((any . "from\\|to\\|cc ...))

So, I figured the `:type' part should be provided. Guess, I got
confused by all these different *Help* buffers, locating all kinds of
functions.

However, the error message remains.

Argh.  I missed the missing single quote:

(add-to-list 'nnmail-split-abbrev-alist
;            ^
;            missing

Sorry.

The matching is supposed to be case insensitive, and according to my
own tests it is.

Yes, in fact I explicitly want case-sensitivity at times, so I have to
use this to get it during nnmail's activities:

(add-hook 'nnmail-split-hook (lambda nil (setq case-fold-search nil)))
