Will the Mail.App (on Mojave) search within the base64 encoded parts of a message with mail rules? It looks like it only searches the text.
I'm not looking for it to decode the base64, rather just search for some raw base64 snippets provided by my rule within the base64 encoded sections.
My goal is to test whether some specific words have been included inside a base64 encoded html email.
It looks like Mail.app skips base64 encoded sections when searching emails via the rules.
