List all cPanel accounts that 'are not' or 'are' using SpamAssassin?

Hi, I'm looking for a way to list cPanel accounts that are not using SpamAssassin i.e. SpamAssassin is disabled for them in cPanel Home > Apache SpamAssassin. Another way would be to list all accounts that are using SpamAssassin, however that will list a lot of them on our server. I can't seem to find a way to do this in cPanel or via the CLI, so any help here will be great. Thanks! Yasser
