I sent mail at one point to all of the users on my list which were not bouncing mail from the demon.ac.uk site. I pleaded with them to tell their postmaster to fix his error message configuration, since it was inundating my lists with hundreds of error messages each day. I had sent a lot of mail to the postmaster there, only to have him respond and say "something must be wrong at your end." Wanker. I know of at least one other postmaster who has also contacted him and not gotten anything done. Will
