This is the most common problem I encounter, and one of the most helpful error messages I'm aware of (one reason I like LISTSERV so much). > You are not authorized to send mail to the ENGLISH- > FACULTY list from your [log in to unmask] account. You might be > authorized to send to the list from another of your accounts, or > perhaps when using another mail program which generates slightly > different addresses, but LISTSERV has no way to associate this > other account or address with yours. That's exactly it. For lists set to subscriber-only posting, Email addresses have to be stored in the exact form as the return address the subscriber is using, and, regularly, university IT folks "clean up" their mailers and change everybody's default address -- changing the internal routing or the form of the user's name. (To be fair, they usually inform users they're doing it, but users don't usually know what it means to their list subscriptions.) Almost as regularly, people change mailing programs and don't know that when they identify themselves they need to have the exact same address, resulting in a situation where they have different return addresses when they're working from their desks and at home. Check the list, see what this person is actually subscribed as, and either change it or tell the subscriber what the problem is. It takes more time than anything else I do as a listowner -- but the alternative is to let anybody post to the list, and that way lies waist-deep spam. -- Russ Russell Hunt Department of English St. Thomas University http://www.stu.ca/~hunt/
