I am the list owner and I keep receivig the following message from the LISTSERV. Even some subscribers got this error message. I tried to delete them but they don't exist. Any ideas? The following 2 subscribers are currently being monitored: Err First Last Address --- ----- ----- ------- 23 09/29 10/08 Joshua Mcmichael <[log in to unmask]> Last error: This userid is not a valid user on our system 23 09/29 10/08 [log in to unmask] Last error: This userid is not a valid user on our system Err= Number of delivery errors received thus far First= Date first delivery error was received (mm/dd) Last= Date of most current delivery error (mm/dd) Subscribers will be automatically deleted from the list when delivery errors have been reported for a period of 4 days or more, or when 100 delivery errors have been received, whichever occurs first. Monitoring will cease after 5 days without any reported error. Note: manually deleted subscribers may remain on the monitoring report under an alias address. Such entries will expire eventually; you do not need to do anything about them. Victor Lavrov INVENTORS
