Between approximately 7:45 and 10:15 EDT today, there was a problem with list mail to Brownvm. Correctly addressed mail for our local redistibution addresses was returned with a "No such user" error. These addresses are usually of the form "xxxxxdst@brownvm" or "[log in to unmask]". We regret any problems this may have caused list owners. If you remember deleting or setting to "nomail" any of these addresses, I'd appreciate it if you could attempt to restore the subscriptions. Peter
