  # https://www.spectrumbusiness.net/support/internet/understanding-email-error-codes
  #   Error codes are placed in one of two categories: incoming or outgoing.
  #   1. If you're trying to send an email to a Charter email address from
  #      a non-Charter email address (such as Gmail, Yahoo, Hotmail, etc.),
  #      you may receive an error that begins with AUP#I, followed by four numbers.
  #
  #   2. If you are trying to send an email from a Charter email address
  #      to an outgoing recipient, you may get an error code beginning with
  #      AUP#O, also followed by four numbers.
  #
  # 1000 Your IP address has been blocked due to suspicious activity. If you're a Spectrum
  #      customer using a Spectrum-issued IP, contact us. If you're using an IP address
  #      other than one provided by Spectrum, blocks will remain in place until they expire.
