No I didn't change the list address. It is not a "mail list" like this one, more of an "announcement list". It is not a 2-way mailing list. The subscribers don't send anything to it for other subscribers to see. It's used rarely to send announcements of event cancellations, etc. About 1000 subscribers manually maintained. But, the users tend to start a (unrelated) communication with us via replying to that announcement list's "reply to" address since that is where they last received a message from us. And so their message does not go to the right person, it goes to the source address of the announcement and we have to sort through them and direct the message to where it should have gone to start with. We just want to let subscriber who incorrectly sends to the announcement list address to use one of the "correct" addresses to communicate with us, not via replying to the announcement list. See? FWIW, we tell them not to do it with a footer and header on every announcement email, but they do it anyway. I'm sure there is a better way, this seemed easy enough to implement. Perhaps and auto-reply type setup to that particular address. I looked at those and they looked more difficult to set up. I'd be grateful for better suggestions. I'll look for a better way to notify them. Thanks very much for the help.
