Hi, I'm getting tons of spam with mail senders or helo names from TLDs like .date, e.g.
Received: from koan-shf.date (unknown [78.129.179.127]) by... where the domain names (here: koan-shf.date) rapidly change and are obviously randomly generated. IP addresses also change daily. I'd therefore like to block TLDs like .date or .loan, which currently does not work with postfix. Following it's manpage 5 access, the block lists for mails and sender machines need at least .domain.tld, i.e. two domain components. This made sense as long as we had country code and the old generic TLDs like com and gov, but not anymore since ICANN allowed any nonsense to be registered as a TLD. I'd like to propose to allow one component queries for mail addresses and hostnames in access lists as well. regards Hadmut
