Many of our lists - lists that are not open subscription, and are confidental - have the following address on their monitor report. This address is not on any of the subscription lists. And it doesn't look like it ever was if I look at the modification date of the .list file. Any idea on what might be happening here? Thanks, Jane Err First Last Address --- ----- ----- ------- 1 03/10 03/10 [log in to unmask] Last error: Unavailable; DSN status was 5.1.1 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.
