i wouldn't have my organization join this cooperative. Why? Because accounts get compromised and spam gets sent. It just does, even with 2FA and NFC dongles and public/private keys. In your cooperative, if two or more of the thousands of accounts in my org are compromised, the entire org loses email? Not gonna happen, even if you tweak the rules to be more lenient. Realistically we will always have spam. It can be reduced but, just like snail mail and all other forms of push communication, you will always get spam. Get over it.
