Feature Request: Better Spam Control

Would love to have more access to spam management. Access to a whitelist/blacklist would be fantastic.

I use a bunch of enviro sensors that are configured to send email alerts based on humidity, temp, motion, light, etc. Sometimes I can receive 0 alerts in a day, sometime dozens. Spam Assassin has decided these alerts are spam and it would be nice to whitelist them, rather than easing up on spam detection and letting more crap through.

Thanks!

Same concern here with IOT alerts.

This is the most important function we need to be able to block domains we are even tired of spam folders , we should add domains to blacklist and we dont ever want to see those messages again block = auto delete forever (not even in trash)
