Thanks for the responses. Larry and Pete suggest turning off auto-delete, which would solve the problem in future, but won't let me solve the immediate issue, which is figuring out how serious this is. How many subscribers have been auto-deleted over the past few months for bounced emails? If they're only a couple, or only ones at that institution, I'll know more about where and how important this is. F.J. Kelley asks, > Has IBM been contacted?

He has suggested the admin at the host of the list contact IBM; I'm hoping they will, and that this will solve the problem. I'd still like to have an idea how widespread the problem has been (ideally, a list of blocked users so I could email them and asked if they'd wanted to be blocked). -- Russ ############################ To unsubscribe from the LSTOWN-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTOWN-L&A=1
