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?
