SmartList 3.11pre4 doesn't interpret "Subject" line

The commands on the "Subject:" line of a message to a smartlist mailing list
are all being bounced back as undecipherable.  For example, the message
created by

  Mail -s subscribe foo-request(_at_)kcilink(_dot_)com </dev/null

will bounce back with the help message.  However,

  echo "subscribe" | Mail foo-request(_at_)kcilink(_dot_)com

works to subscribe the user.  So it seems that the 3.11pre4 SmartList is not
picking up commands from the Subject line.  Similar errors occur when
attempting to "get file" from the archive -- the commands on the subject
line are ignored.

I'm running procmail/SmartList on BSD/OS 2.0.1 (aka BSDI).

Thanks.
