Here is milter code to check for the number of recipients.

----------------------8<------------------
import Milter

class myMilter(Milter.Base):

  ## Provide simple logging to sys.stdout
  def log(self,*msg):
    print 'Milter:',
    for i in msg: print i,
    print

  @noreply
  def envfrom(self,f,*str):
    self.log("mail from",f,str)
    self.recipients = []

  def envrcpt(self,to,*str):
    # mail to MAILER-DAEMON is generally spam that bounced
    for daemon in ('MAILER-DAEMON','auto-notify'):
      if to.startswith('<%s@'%daemon):
        self.log('REJECT: RCPT TO:',to,str)
        self.setreply('550','5.7.1','%s does not accept mail'%daemon)
        return Milter.REJECT
    self.recipients.append(to)
    self.log("rcpt to",to,str)
    return Milter.CONTINUE

  def data(self);
    if len(self.recipients) > 1:
      for to in self.recipients:
	if to.lower().startswith('<abuse@'):
	  self.log('TEMPFAIL: abuse')
	  self.setreply('451','4.7.1','Please email abuse by itself.')
	  return Milter.TEMPFAIL
    return Milter.CONTINUE
