Hello Colton,
Thanks for your inquiry. Can you please confirm the version of SmarterMail that you have ? I'm not certain on why the Content Type spam checks are continuing after the message was detected to exceed the scanning size. Please let me know if there are any other examples of this and we can review. You may want to consider opening a Support Ticket for us to evaluate the details in the logs and the specific email that was scanned.
Thank You.
