Per some suggestions here, I set List-ID= tango for my list tango which was renamed to tango-L, so that people who still tried to subscribe under the old name would not get simply a "this list does not exist" message. However, this does not work, as a test "review" and "signoff" command done after I had PUT the header verified. Does this take some time to take effect (e.g., overnight)? Does the postmaster also have to set up something? (The new draft "Keywords" document did not suggest either.) By the way, e-mail sent to the old list address [log in to unmask] or the administrative address [log in to unmask] does get forwarded to the respective -L addresses, but that was true even before I set up "List-ID= tango" so I think the postmaster set it up as an explicit alias. But any listserv commands on the old list name tango returns a "No list by this name" message. What am I doing wrong? Thanks. Shahrukh Merchant
