Advanced Scoring Syntax with "To" and "Cc" Headers

Advanced Scoring Syntax with "To" and "Cc" Headers

[Husain Alshehhi]

From the documentation[1], one can configure complex rules through and,
or, not operators. The documentation also states that match operators
are "header name strings followed by a match and a match type". The
documentation also provides examples[2].

However, all the docs and the examples provide the simple "from",
"body", "subject", "line" match operators. I am unable to create rules
that use "header" or "extra" operators. Ultimately, I want to setup a
rule that scores an message based on the (1) "from" header AND "to"
header, (2) "from" header AND "cc" header, (3) "from" header AND an
arbitrary header.

gnus errors out when parsing the following rules:

--8<---------------cut here---------------start------------->8---
((&
   ("from" "example@domain.com")
   ("to" "example@domain.com")) 10)

((&
   ("from" "example@domain.com")
   ("header" "example@domain.com" "To")) 10)

((&
   ("from" "example@domain.com")
   ("header" "example@domain.com" s "To")) 10)   

((&
   ("from" "example@domain.com")
   ("extra" "To: .*example@domain.com")) 10)
--8<---------------cut here---------------end--------------->8---

Any help is appreciated. Thanks.

Glad it worked.

It seems that you cannot use `extra' match in advanced scoring at
all (see `gnus-advanced-index' variable).

Thank you. This seems to be working.

But performance is the main reason I use "extra" for CC and To (after
setting gnus-extra-headers). Is there an equivalent syntax for using
"extra" matcher?

Hi, I think that this is the syntax you're looking for:

(((&
   ("from" "Eric Abrahamsen")
   ("head" "Cc: ding@gnus.org" s))
  1000))

Please note that scoring on "non-standard" headers takes
a while.

Best

My understanding is that the matches that look like this:

>    ("from" "example@domain.com")

should have the second argument be a list, so something like

>    ("from" ("example@domain.com"))

might do the job?  I've never used the logical operators you are trying
to use however.
