I have a problem that I'm not certain how to address. On one of my mailing lists, I have been getting persistent error messages from America Online, to the effect that "[log in to unmask]" is an unknown user. However, there is no such user listed as a subscriber on the list in question. If I try to delete the specified ID, LISTSERV tells me that there is no subscriber with that address on the list; similarly a query for *@aol.com shows no such subscriber. Yet the error messages keep coming in, indicating that current messages are somehow getting directed to that address. Any suggestions? -- Lefty [gYon-Pa] <[log in to unmask]> C:.M:.C:., D:.O:.D:.
