Here at Ryerson we are going through our annual end-of-semester spool clutter. Every semester students will signup to mailing lists and forget to signoff when they leave for the summer. Has anyone developed software to examine the rdr's of expired accounts and auto-delete them from mailing lists?. We are planning on developing a program to do this for us and would prefer not to re-invent the wheel. How do other institutions handle mailing lists cleanups after students have graduated/left for the summer?. thanks in advance for any programs/info you can supply. /Paul ACS - Ryerson, Toronto.
