  34 <PRE>     Another thing that should be mentioned about the sendmail module is
  35 that it blocks until the sendmail process exits, which can cause
  36 significant problems if your sendmail program does anything other than just
  37 queue the message.  To be honest, I only wrote the sendmail module as a
  38 backup in case the SMTP module couldn't be used for some reason (like a
  39 site that doesn't use SMTP for mail).
