Apple Mail: spam filter works, but which one?

Question

Apple Mail

Hello everyone
I have a whole system of spam filters set up in Mail. And it changes and grows as new spammers emerge that are resistant to external spam traps.
At some point, all this became so ramified that now I cannot determine by what particular criterion Mail determined the necessary letter to spam in order to soften this criterion and return all such letters to the inbox.
Maybe dear dons know how to see the Mail report on making this decision?
merci
