To my knowledge, the idea of hash blocklists was first publicly proposed in M3AAWG 41, October 2017. https://msbl.org/ebl.html has the details. Ever since, Spamhaus HBL has come up (to address not only email addresses but also files and cryptocurrency wallets) and it seems that even more people have taken up the mantle now. -- Atro Tossavainen, Founder, Partner Koli-Lõks OÜ (reg. no. 12815457, VAT ID EE101811635) Tallinn, Estonia tel. +372-5883-4269, https://www.koliloks.eu/ ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop

I get a great deal of spam that says to respond to a dropbox somewhere else. If they're looking for those dropboxes, that makes some sense. Yes, there are joe jobs. No, there are not very many.

[mailop] how does mailhash.josephlist.net work?
Hi List I came across emails rejected by mailhash.josephlist.net reason: 550 5.7.1 block listed email address s...@example.com by mailhash.josephlist.net (c559b92e0e284312b26c88d4bb707d14) What I found out is that the email content is searched for email addresses and if some hash of that email address matches, the email is rejected. It's the full email address. Only the domain part does not trigger the issue. The hash at the end of the error message looks like an MD5 hash. But that hash does not match (tested lower and upper case) the email address listed. Also, if I send two email containing the email address triggering the block, I get two different hashes. So maybe the hash is not derived from the email address? Does anyone know how mailhash.josephlist.net operates and the reason why they list hashes of email addresses found in email bodies?
