For crying out loud!  Did you even *look* in the "INSTALL" file?
Right there in plain fiew:

    Problem:  I send mail to the list, and get back mail saying,
              "sh: wrapper not available for sendmail programs"

    Solution: Your system uses sendmail restricted shell.  You need to
              configure smrsh by creating a symbolic link from the
              mail wrapper ($prefix/mail/wrapper) to the directory
              identifying executables allowed to run under smrsh.
              Some common names for this directory are
              /var/admin/sm.bin, /usr/admin/sm.bin or /etc/smrsh.
              Note that on Debian linux, the system makes
              /usr/lib/sm.bin, which is wrong, you will need to create
              the directory /usr/admin/sm.bin and add the link there.
              NOTE: any aliases newaliases spits out will need to be
              adjusted to point to the secure link to the wrapper.

Does this not completely answer your question?
