title: Python SMTPLIB remove X-CMAE-Envelope on all messages SMS
body: <p>I am using SMTPLIB in python for sending sms messages and I wanted to know why some of my messages are sending with a <code>X-CMAE-Envelope:</code> header and how to remove it. I am using this python code for sending messages through sms: `</p>
  <pre><code>import smtplib
  
  
  carriers = {
      'att':    '@mms.att.net',
      'tmobile':' @tmomail.net',
      'verizon':  '@vtext.com',
      'sprint':   '@messaging.sprintpcs.com',
      'alltel':   '@sms.alltelwireless.com',
      'boost':   '@sms.myboostmobile.com',
      'cricket':   '@mms.cricketwireless.net',
      'metropcs':   '@mymetropcs.com',
      'uscellular':   '@email.uscc.net',
      'virginmobile':   '@vmobl.com',
      'republicwireless':   '@text.republicwireless.com',
  }
  
  def send(message, phonenumber, phonecarrier):
      to_number = str(phonenumber + carriers['verizon'])
      auth = (EMAIL, PASSWORD)
      server = smtplib.SMTP( &quot;smtp.gmail.com&quot;, 587 )
      server.starttls()
      server.login(auth[0], auth[1])
      #msg['From'] = &quot;TEST&quot;
      server.sendmail(auth[0], to_number, message)
  
  
  messagetext = 'Test'
  send(messagetext, phonenumber, carrier)
  </code></pre>
  <p>Also I was wondering with sms/imessage if it is a possibility to add the contact name functionality to this code such as &quot;siri found contact info: COMPANY NAME&quot;. Thanks for any help in advance!</p>
