How to filter Gmail messages to labels on advanced headers?

[Robert Andrews]

Gmail's in-built search feature does not apparently support advanced headers.

I would Gmail to automatically identify messages matching certain criteria. Namely, those which come via but not from distribution services like PRNewswire and Gorkana.

Take the following header from one such message...

ARC-Authentication-Results: i=1; mx.google.com;
       spf=pass (google.com: domain of sprbounce+b32$vzzjfltltby3gn4q5jhxjipjsi======@gorkanadatabase.com designates 85.158.142.4 as permitted sender)
smtp.mailfrom="sprbounce+B32$VZZJFLTLTBY3GN4Q5JHXJIPJSI======@gorkanadatabase.com"
Return-Path: <sprbounce+B32$VZZJFLTLTBY3GN4Q5JHXJIPJSI======@gorkanadatabase.com>

We could choose to check the field "Received-SPF" for the string "gorkanadatabase".

How can this be done with Script?

I have seen that it is possible to use Scripts to check and apply labels to incoming Gmail messages - eg. https://www.labnol.org/internet/advanced-gmail-filters/4875/

But I don't understand how to implement this in my case.

Thank-you.

Such filtering is much lower in the Google code base and not made available as far as I know.

These are the controls that Google uses to accept, reject or flag spam emails to the overall user base.

They would not want us disturbing that process.
