Spam filtering by Scrip before On Create sends notification mails

Hey,

we try to implement a spam filter after the removed deprecated Mail-Interface and we like the approach to use a Scrip for that purpose:
https://rt-wiki.bestpractical.com/wiki/SpamFiltering#b.Pre-filtered_mail.2B_Scrip_.3D.3E_Queue

We would like to “move” such emails to a dedicated spam queue.

Unfortunately, our AdminCCs and Watchers still receive a notification mail. Is there a possibility to trigger that filter before the notification got send?

Cheers

Roman
