    I am seeing Google constantly fail to catch obvious spam emails. At this point I suspect there is some institutional error on their part, where bad actors inside the org are allowing certain domains to simply not be spam filtered.

    Looks like a very personal list. I would not advice anyone using this as part of anything. Rohith[1] is in India and most of the spam domains (did a quick split) in the list are similar sounding names of a lot of Indian companies/Startups. Not that the companies do not spam (they do) but emails/domain registration has become so easy that there are tiny setups/operations in every nook and corner of the streets/chawls/shanties of India trying to spam people.

    In theory one can set any domain to "from" field, what about actual servers that sent the spam? How many of those spam emails have unsubscribe and/or complaint headers?

    I have a similar list: https://gitlab.com/cmiksche/blacklists/-/blob/master/hosts

    Did you think about adding your list to well known blocklists? You can add it to e.g. OISD

    These are usually domains that belong to a disposable email service, be it public or private.

    I maintain a 100% free API [1] to check if an email belongs to a disposable email service. We dogfood the same API endpoint to prevent users who abuse disposable emails to create fake accounts for free trial credits.

    We use the domains found at https://www.stopforumspam.com/downloads amongst other sources of data. Works pretty well. We have close to eliminated fake account registration with the use of Recaptcha.

    I am surprised to see Washington state university emails used for spam to that extent.
