Thanks for your question about lowering the filtering level. This appears to be a question about filtering in email, but if it isn't, then please provide more information about your question and we can investigate the issue in further detail.
You can learn about using Email Filters in cPanel through our Support Center website. Note that filtering can be done through cPanel, but it can also be done directly in your email client. You may need to look at your email client application's documentation to learn more about how you can modify the filtering settings in that software.
I hope this helps to answer your question. If you need further assistance, please let us know!Kindest regards,Arnel C.
