I've searched the archives and didn't come up with much for an answer so.. I'm having a problem with a user who cannot post to a list which is subscriber-posting only. The error generated says: --------------------------- You are not authorized to send mail to the xxxx-L 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. If you need assistance or if you have any question regarding the policy of the xxxx-L list, please contact the list owners: [log in to unmask] --------------------------- The header for this users mail looks fine except that "Sender:" is "Sender: smith" What I think it should be is a valid subscribed email address like "Sender: [log in to unmask]" Would this cause LISTSERV to not recognize the user and therefore the error? Thanks, Dan
