Server at receiving end reports "user unknown."  Global delete of bounced
address from our lists finds "no action taken."  Is the most likely
scenario that a user subscribed under one address, had mail forwarded to
another address without signing off the list, then signed off the second
address?  Any other scenarios?

Short-term solutions?  Long-term?  Can the manager set all lists to
periodic quiet probes?
