This works for me:

acl_smtp_mail = acl_check_mail
  # smtp mail [4-3]: Deny the authenticated sender if the authenticated id
  #                  does not match the sender address.
  deny    authenticated = *
          condition     = ${if eq{$authenticated_id}{$sender_address}{no}{yes}}
          message       = Your authenticating ID must match your sending address.
          log_message   = 4-3: Authenticated ID ($authenticated_id) does not \
                          match the sending address ($sender_address).

If at first you don't succeed... much for skydiving.
