I think you are missing the fact that regex applies only to the message
BODY and not to the headers (as explained in Sect 40.4, although in
39.20 it is not 100% accurate).
I guess that the way to do your check would be using the header
expansion items (Sect 11.5) with something like:
accept condition = ${if match{$h_to:}{\N.*nospam-.*(\n|\r\N)}{yes}{no}
accept condition = ${if match{$h_cc:}{\N.*nospam-.*(\n|\r\N)}{yes}{no}
[I am not sure of the answer because I don't have any means to
test it now]
