i have noticed that some ietf working groups don't anymore allow postings except from addresses that have subscribed to the list. this not good unless there is a way to register another email address from which postings are allowed. the reason is that many people don't want to get any mailing list traffic to their personal mail boxes and therefore have subscribed an alias rather than their own personal email address. could it be made a policy of ietf mailing lists to include support for a posting address that is not the same as subscription address? some mailing lists already do this, but not all. -- juha
