Correct. But Reply-To doesn't mean "follow up with list posts to this address"; it means "I don't want private replies on this list, ever". The relevant header for normal list follow-ups is List-Post. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup. To reply privately _only_ on Usenet and on broken lists which rewrite From, fetch the TXT record for no-use.mooo.com.
