I'm subscribed to the postfix and spamassassin mailing lists and they are closed.
I think those 2 lists have a lot to do with email.
This is the only list i'm on that got hit by that german spam bot..
maybe you shouldn't discount every option to filter spam as "not worth the effort" or "they can get around it somehow".
you'd be surprised at how far just basic checks and filters can go..
