The machine has a name like (/etc/hosts entry): reader.local.lan 192.168.xx.xxx reader There must be several (100/1000 ?) that could possibly have that FQDN. How is this uniqueness obtained? If I allowed gnus to generate the Message-ID (rhs) by its own devices, then it would be: Message-ID: Instead of: Message-ID: Hard to see how either of these can be guarranteed to be unique any more than: Message-ID:
