  69 <th>NOTES</th>
  70 <td>
  71 <ul>
  72     <li>Since the message body may be very large, setting SMFIF_CHGBODY may significantly affect filter performance.
  73     <li>If a filter sets SMFIF_CHGBODY but does not call smfi_replacebody, the original body remains unchanged.
  74     <li>For smfi_replacebody, filter order is important.  <b>Later filters will see the new body contents created by earlier ones.</b>
