[Rspamd-Users] Control rspamd depending on subject content

[Andreas]

Hello,
To avoid annoying spam that gets through Rspamd, I wrote this script

#!/bin/bash +x 
if [ ! $UID = 0 ] 
then 
       /usr/bin/su - 
fi 
/usr/bin/echo "$1" >> /etc/rspamd/local.d/maps.d/sender_domain_blacklist.map 
/usr/bin/systemctl restart rspamd.service

 which unfortunately still has to be fed with the domains manually.
Most emails have typical phrases such as “r_ezept-frei”, “Rezept-frei”, “pharmacy”, Pharma” 
in the subject.
Can Rspamd be configured similarly to the script shown so that a reject is triggered 
immediately depending on special terms in the subject?

Thanks and Regards

Andreas
