You can't add headers in user filters, but you could try to trick it
inside of the router.
user_forward_router:
...all your usual stuff here...
headers_add = ${if >{$n0}{0}{X-Filter-Failed: $n0}{}}
and use
"add 1 to n0"
in your filter, whenever you want to add the header.
I'm not sure if this works, but you should try it ;)

For spam-scanning you should use something more advanced, like spamassasin.
