Yes.

Exactly, with suitable leading whitespace on lines after the first if it
is not all on one line:
spamfilter unix - n n - - pipe
flags=Rq null_sender= user=spamfilter
argv=/usr/local/bin/spamfilter.sh -f ${sender} -- ${recipient}
Check the script to make sure it does not break with an empty "-f"
option value. If spamfilter only uses the command-line arguments
for re-injecting into sendmail(1) and otherwise only looks at the
message content (not envelope) you are done. Otherwise you need
to see how it parses/uses the "-f sender" option.
