disabling Zoho's obstructive "spam" filter

spam filters are supposed to be helpful, but Zoho's "spam" filter does nothing but make work for me as 99.9999% of the messages it catches are false positives, and the only way to change the filter's behavior is on a message-by-message basis (this is incredibly poor design, folks). i've already been informed that there's no way to disable this broken filter (another major design flaw) and i have a perfect spam filter of my own running on all my computers and don't want or need Zoho's "help" controlling spam, so i want some way - any way - trick Zoho's broken filter into getting out of my way and staying there. is there a wildcard i can put into the whitelists so that all incoming email will automatically be seen as being on my whitelists?
