Spam filtering in Zoho is inexistent, I am getting 100% of the spam, none is filtered by default. In comparison, G Suite filters 99% of the spam. I am getting to the point where I am ready to switch if I can't find a solution.
I am getting hundreds of spam emails in streams. They remain in streams regardless if I mark them as spam on a particular email address. I can set a filter to move these emails to deleted folder (but cannot mark them as spam, what's up with that?!?) for individual email addresses but not for the stream itself. That forces me to create the same filter for each email address which is a lot of work. Most of these emails have same or similar content, but sender's email address changes all the time so filtering the domain won't work but phrase filtering will work. Is there a way to filter these spam emails at the stream level and once marked at spam, take them off all stream users emails?
