Email Filters based on attachment

Is there a way to filter emails based on the name of their attachment or the content in an attachment? I would like to filter out emails that have an attachment with the name that contains X or, if they have X in the text in the attachment. Preferably without any coding, perhaps a plugin?

  Hello Carl-Johan Larsson, As of cPanel's last knowledge update regarding email Filters, in September 2021 & July 2022, cPanel itself doesn't offer built-in features for filtering emails based on the content on attachments. Configure Email Filters Other than that, you can create a custom filter rule file, this might would be helpful for you. 1. This would catch every email with any type of attachment. But be warned, that includes signature images and a host of other benign files. The better option is to filter out specific types of attachments. Body - Contains Content-Disposition: attachment; 2. Would catch anything with a .zip file attachment. Body - Contains Content-Type: application/zip; OR Body - Contains Content-Disposition: attachment; AND Body - Contains .zip

  I would agree that some level of custom filtering through Exim is the best option, as there is no native tool available to filter based on attachment.
