As Listowner, I receive all "error" messages to the Mailing Lists which I manage. Sometimes, when I feel the messages need to be posted to the Lists immediately, I will go ahead and forward them. In the From: header, you will see the original sender's email address and a (by way of "George W.Durman" <sgtgeorg@concentric.net>). There are several reasons why this is necessary. Here are a few examples: 1) The sender sends to an address that contains "-request" in it. Such addresses are only for subscribing and unsubscribing. Here are the correct formats for them: LISTNAME-L-request@rootsweb.com (For subbing and unsubbing.) LISTNAME-L@rootsweb.com (For posting messages.) In the above example, "LISTNAME" would be replaced with the List's actual name, say "BROYLES", "GERMANNA_COLONIES", "WILHITE", etc. In this example, just make sure you leave out the "-request" part of the address. 2) Sometimes a user subscribes with one address and his/her ISP or email service uses a slightly different "dynamic" form. Example: JohnDoe@whatever.net (User subscribes with this address.) JohnDoe@mail.whatever.net (ISP adds the "mail" part.) JohnDoe@email.whatever.net (ISP adds the "email" part.) In this example, you need to find out from the ISP what the EXACT form of the address is going to be from the ISP; then, subscribe with THAT form. 3) Users subscribe with one valid email address, but have one or more other addresses. They then send email from one of the other unsubscribed addresses. This causes "not a subscriber" error messages to the Listowner. In this example, you need to let the Listowner know what the other addresses are that you might be using from time to time, so he/she can add those unsubscribed addresses to the "Accept List" for the Mailing List. This will not result in duplicate copies of posts, but will ensure that you can send email from any of the other addresses. This note from me is just a reminder to read the Welcome Message that you receive. It gives the proper addresses for subbing and unsubbing and for posting email. And, PLEASE when you send me a notice that your email address has changed, and you want me to unsub the old one and re-sub the new one, PLEASE, PLEASE give the old address and tell me which Lists you are subscribed to!!!!! It really helps and saves me from having to reply and ask for the information. Regards, SgtGeorge Listowner
