This has happened to me on numerous occasions when I e-mail the entire list.
I would assume that there is an e-mail recipiant or 2 with expired e-mail
addresses or some other problem with their address which causes the
bounce-back and error message. I've seen this many times before on other
lists and this was the case.

>Ditto, I get an average of two error messages from two different sources
per
>post. Figured I was the only one.
