Thanks for the information. But here's the deal. Even your Email seemed to originate from hunt-bounces@rootsweb.com instead of hunt@rootsweb.com or the hunt-list@rootsweb.com . My question is, why did it come from the bounces part of rootsweb? I thought that was an "internal" part of the website. Any more on this would be appreciated.

Hunt Sent: Tuesday, January 02, 2007 1:38 PM To: hunt@rootsweb.com Subject: Re: [HUNT] double messages Being a computer professional who hosts *many* email servers, I would think that "hunt-bounces" is a part of the list server that acts as a mailbox to receive non-delivery reports or "bounces" for outgoing emails from the list that cannot reach a recipient. A bounced message is one that gets a failure to deliver email back from either the destination mail server (if it exists) and the intended delivery mailbox either doesn't exist or it cannot be delivered to... Or from the originating server if it cannot even reach the destination email server. A bounce mailbox is a sort of "automatic" housekeeping system. It sends on behalf of you when you post to the list... So you, as a sender and member of the list, won't have to deal with the non-delivery reports. Imagine if the list had over 100,000 members and about 1,000 or 1,500 of the email addresses were no longer valid. If the list server did not act as the middle-man for delivery... You as an individual would have to receive all of the failed delivery messages. Internally, the bounce mailbox at the list server can then deprecate the particular 'bad' email addresses and after a certain number of failed delivery attempts, it can remove the member from the list or try to send a message to the user separately to let them know there is a delivery problem to them. If they don't answer, they get deleted from the list. If we all had to manage this ourselves, it would be a huge pain. :)
