I know this has been discussed before, but this one has me stumped. Based on past discussions, I have learned to ignore these mystery addresses, and most of them usually go away, but as you can see, this one is really persistent. _______________________________________________________ Err First Last Address --- ----- ----- ------- 301 11/09 01/28 [log in to unmask] Last error: SMTP; 550 MAILBOX NOT FOUND Subscribers will be automatically deleted from the list when delivery errors have been reported for a period of 5 days or more, or when 25 delivery errors have been received, whichever occurs first. _______________________________________________________ I have never had a subscriber with this address, and I cannot track it to any existing addresses. Why doesn't LISTSERV get rid of it if there are 301 errors and it has been going on for nearly three months? Is there anything else I can do?
