[log in to unmask] James Barnes, Jr. [log in to unmask] Barbara Semonche [log in to unmask] karen c blansfield ----------------- Here are the error messages I have been getting from the mailer and PSU: PSUVM.PSU.EDU unable to deliver following mail to recipient(s): <barnes@tipper<.oit.unc.edu> PSUVM.PSU.EDU received negative reply: 550 <[log in to unmask]>...

Surely if there have been changes at the site they should have been aliased so that the list would not get such bounces needlessly?
