You can't.
Version 2.4 of YAM has been modified by some well-meaning programmer to change the behaviour of the filters. In version 2.3, the filters could be applied to remote emails (on the server) AND to emails already received and in the "Incoming" folder. In version 2.4, if the "Remote Filter" attribute is set, the filter no longer works on already-received emails.
What this means is that a filter that checks for "html" in the body of the email won't work remotely (because only the header is accessible), and won't work locally if the Remote bit is set.
You may be able to do it by having TWO identical filters, one with the Remote bit set, that operates on email headers at the server and one without Remote set, that operates on already-received emails.
