And maybe spamfiltering should be forbidden at that level. Because the entry in that field for companies is very hard. You can't buy your own spamfiltering for Google, Hotmail or ISPx. And something else is at play too: ISPs don't give much for your email. They rather overblock than underblock. It is often seen as a cost only. 50% of ISPs do a poor job at filtering.

One example: I would like a DMARC test in my spamchecker. Good luck convincing your ISP if they don't have it.

But to come back to your argument: Filtering should only be done at the request of the user/buyer of service (and/or therefore necessary for the security of the ISP).

There is no 'best' way to spamfilter bad emails. The definition of spam is unknown and being redefined constantly by spamfilters (which is a little different from what recipients think spam is).

The problem is that the process of 'what is spam' is quite complex for humans. For instance: Suppose I gave you permission to send me bulkmail and you only start to use it two years later. Is that spam? For one person it isn't, for the other it is.

No, DMARC authenticates you as a sender to fight phishing but does not tell you what the rest of the spamfilter concludes. You can still send spam using DMARC. The reporting feedback of DMARC is necessary to find problems in the authentication. An added bonus is that you can identify spammers.

Microsoft has SNDS which is pretty helpful in finding moments when things go bad. It does not identify your customers, I have to find that myself.
