It is common knowledge that Zoho's spam filtering is very sub-par. As a result, I find that I need to do it myself, however I'm too limited. I have filters in place to send many spam key-words directly to trash, but I can only do that if they're in the subject line of the email (for example "YOU HAVE WON" and "YOU HAVE BEEN CHOSEN", this kind of nonsense.
However, if the email header looks OK, but the body of the email contains such phrases, there's no way to filter the emails according to body content. Why?
I'm so sick of spam, and I'm so sick of Zoho's spam system not learning to identify OBVIOUS spam. Now I find that I can't even teach it myself. Very frustrating. I'll give Zoho a few more months maybe but that's it if this isn't fixed.
