After searching, I couldn't find an effective way to identify and delete/move Junkmail from Evolution automatically.
I did come across this web page that discusses Evolution filters for email headers:
Filters
Armed with this info and the following topic I found on the subject from a developer:
commands
I came up with a DMARC filter that helps identify a great deal of Junkmail I've been receiving.
Works well and, as you can see, is quite customizable for identifying Junkmail and then taking action.
Hope this helps.
