> But it's good to know: Hopefully SPAM filters start looking for 3xx redirects and blocking all email that comes from a domain with a 3xx redirect.
I believe some already do. As a consequence, instead of doing redirects, the recommendation is now to use a landing page on the domains. I assume next the spam filters will start checking the quality of content of the domains, if they don't already. It's a never ending game of cat and mouse.
