In the daily error monitoring report for one of my lists, two of the subscribers reported as being monitored don't exist. How and why does that happen? Can this be explained at a superficial level? I noticed because the email addresses were obviously bogus: 1 09/01 09/01 [log in to unmask] Last error: Domain "RNAGTLTELGT.ORG" doesn't exist. 1 09/01 09/01 [log in to unmask] Last error: Domain "RNAGTLTELGT.ORG" doesn't exist. (I don't have access to any more details about this transaction that what is listed in the report. At least, not that I know of, or that I know how to get.) Christine in Littleton, Massachusetts
