JG - how to filter spam in email client?

Has anyone worked out how to safely and reliably identify from the header a spam marked by JF? For configuring email clients.

The DH version is missing SpamAssassin’s expected “X-Spam-Flag: Yes”. And is not reliably setting “X-Spam-Status: Yes…” e.g. doesn’t on a blacklist hit.


(DH, how about adding the definition of this simple but all-important interface to the docs?)
