Here is what I use for this problem:

acl_check_data:
  deny    condition     = ${if or 
{{!def:h_Date:}{!def:h_Subject:}{!def:h_To:}}{yes}{no}}
          message       = Message does not conform to RFC2822 standard 

  deny    condition     = ${if eq{$h_Subject:}{}{yes}{no}}
          message       = Messages with blank/empty subjuect line are not 
accepted 

This works perfectly on my system.
