  According to SparkPost support, the errors indicate possible email\_rfc822 content issues. SparkPost suggested confirming if the email\_rfc822 attribute is set in the content object of our transmission (i.e., within CiviCRM).
  
  Documentation re. email\_rfc822 attribute was provided:
  <https://developers.sparkpost.com/api/transmissions/#transmissions-post-send-rfc822-content>
  
  As the configuration was reviewed, it was discovered that a very silly but obscure config error on the server was the issue; when cron runs, it was ignoring some configurations and trying to use SparkPost's server.
