In the last weeks the Zoho spam filter is not working. I am getting bombarded by spam just in the last few weeks, I am reading here about blocked domains and such but that is not how antispam is supposed to work as it is simple to defeat such things. Antispam that works uses a Bayes algorithm that is built up as people report spam. So is that system not working? Can someone at Zoho verify that they do not have a problem with their system? Who does Zoho use for a spam filter? It should be a system that works, like SpamTitan.
I pasted some mails with header here so you can see a few examples of items that should have been marked as spam:
