I agree with David Sitman's recent posting favoring unsubbing bounced addresses vs. the alternative(s). I immediately delete most bounced addresses these days, because some systems generously shower me with rejections for up to 13 days after the initial failure to deliver. Most often (always?) the rejections include the full text of the rejected message. As Yogi Berra said, "it's deja vu all over again." Perhaps patience level depends on one's job. If I were a comp. center employee, I might feel differently. But to get rained on often because someone hasn't bothered to sign off a list or clean up their mailbox just isn't worth it. BTW the subscribers haven't complained, and the Renewal feature seems to be working well on biosph-l (set at 4-Yearly). -dave phillips
