Thank you Per. My problem was I wasn't requiring relational. With it,
this works:

if date :originalzone :value "le" "date" "date" "2018-10-26" {
        fileinto "SPAM";
        stop;
}

I am sorry for the noise. Obviously, anyone using the above snippet will
need something to modify the date on a regular basis so it is say 90
days in the past or what not.

Thank you again.

Trever
