If the major .com outfits agreed to "bounce" mail from previous subscribers or full mailboxes the same way, it may be very easy to set up a filtering mechanism on LSOFT's end. Old addresses could be automatically deleted and full mailboxes could be set to NOMAIL. When the .com people inform the people whose boxes are full, they can add a line re: subscriptions may have been put on hold and to refer them to a -local- area for instructions to restart list MAIL. This would solve the ISP's problems with privacy and help the listowners out at the same time. It would require cooperation and teamwork between LSOFT and the big .com people to set a simple standard, and adjust it on a need be basis. Maybe this would serve a good topic for the listowner seminar being planned? Ray
