You need to define "false positive" more clearly. Consider:
Remote sender A wants to send a mail to our recipient B. Our
recipient B wants to receive mail from sender A. But the mail is
broken in some material sense (e.g it contains a broken MIME
container; a syntax error in a CC: header; whatever), and we reject
it.
From the standpoint of A and B, that was a false positive. From a
mail admin point of view, it was an accurate diagnosis of a broken
mail.
