I have not received a NDR for this user. I think I have used debian-user recently enough that I might encounter one. When I receive multiple NDRs like that, I forward it to the mailing list administrator (along with the original message), and ask the user to be removed from the list. The user can re-subscribe once they clear up their issues. The list administrator can be reached via <listmas...@lists.debian.org>. Jeff
