Yeah you can ignore that. I only included that code because I already had it 
written, and 1 second precision isn't that great for this kind of thing. It 
basically buys letting you do float comparisons in a few shells without 
throwing errors in others.

I was making an assumption that you wanted files matching that pattern. The 
point being that you should not use grep to filter files matched by find. It 
sounds like what you actually want is either:

a) for find to not descend into directories that are not named "new".
b) to match only regular files that have some parent directory named "new".


"b" is pretty easy, just use -path. Code will be:

        find . -type f -path '*/new/*' -printf ...

"a" is harder (I had to think about it). You'd have to use -prune. In that case 
that part of the code would end up looking something like this:

                ...
                find . -type d -path './*/*' ! -name new -prune -o -type f 
-printf '%Ts\0%p\0' |
                        while IFS= read -rd '' mTime && IFS= read -rd '' 
fileName; do
                                (( mTime <= startTime )) && continue 
                                mv -f -- "$fileName" "$tmp" 
                                spamc <"$tmp" >"$fileName" 
                        done

                rm -f -- "$tmp"
                ...
