Surprised to not see gmail.com in the list[1].<p>[1]: <a href="https://drewdevault.com/2021/02/25/Gmail-is-a-huge-source-of-spam.html" rel="nofollow">https://drewdevault.com/2021/02/25/Gmail-is-a-huge-source-of...</a> , <a href="https://news.ycombinator.com/item?id=26265329" rel="nofollow">https://news.ycombinator.com/item?id=26265329</a>
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.<p>1. <a href="https://drive.google.com/file/d/1Z7bBo_rMQB0nJYUs8wl4pZeZVUv6l6eH/" rel="nofollow">https://drive.google.com/file/d/1Z7bBo_rMQB0nJYUs8wl4pZeZVUv...</a>
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: <a href="https://gitlab.com/cmiksche/blacklists/-/blob/master/hosts" rel="nofollow">https://gitlab.com/cmiksche/blacklists/-/blob/master/hosts</a><p>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.<p>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.<p>We use the domains found at <a href="https://www.stopforumspam.com/downloads" rel="nofollow">https://www.stopforumspam.com/downloads</a> amongst other sources of data. Works pretty well. We have close to eliminated fake account registration with the use of Recaptcha.<p>[1]: <a href="https://nubela.co/proxycurl/disposable-email-checker-api" rel="nofollow">https://nubela.co/proxycurl/disposable-email-checker-api</a>
