text: I'm getting a strange error when I send email through Python using SMTP.
  I get an email from Mail Delivery System in my GoDaddy inbox with the error:
  [Return Code 550] sid: Xtpe1o00e3l0Tyx01 :: 5.7.1 more information. ye4si18523263pbb.103 - gsmtp
  import smtplib
  server = smtplib.SMTP_SSL('smtpout.secureserver.net', 465)
  print("Logging in: ")
  server.login("username", "password")
  subject = "This is a test email!"
  msg = "Sample email message"
  text = 'Subject: %s\n\n%s' % (subject, msg)
  fromaddr = "fromemail"
  toaddr = "toemail"
  print("Sending email...")
  server.sendmail(fromaddr, toaddr, text)
  server.quit()
  Warning: Wild guess from incomplete data
  Your email is being rejected as spam. Ensure your email is RFC2822-compliant. Quoting the standard:
  The only required header fields are the origination date field and the originator address field(s).
  In your case, add at least
  From: and
  To: to your outgoing email:
  text = 'From: %s\nTo: %s\nSubject: %s\n\n%s' % (fromaddr, toaddr, subject, msg)
  and confirm that smtplib automatically adds the
  Date: field.
