You probably have "receive_override_options = no_address_mappings" or
similar configured in the before-queue smtpd.

For efficiency, most users use the "advanced" SMTP-based content filter,
rather than the "simple" pipe-based filter.
- Are you expected exactly one recipient per-invocation of the
spamassassin filter? I'm not sure how spamc handles multiple
recipients after "-u".
- You're missing the "--" before ${recipient}, relying only on
"allow_min_user = no" to protect the sendmail(1) command-line
from option argument injection.
