Coupled with something like this in the MAIL ACL to disallow the sending
of mail without saying HELO:

  # Don't allow any MAIL commands without HELO or EHLO
  deny    condition    = ${if !def:sender_helo_name {1}{0}}
      message    = You must identify yourself with HELO or EHLO before sending mail.
