I evidently don't understand Probe as well as I thought I did. I have two lists, one a sub-sublist of the other. They are part of a superlist heirarchy, so the superlist has 23 sublists which are also superlists, drawing on about 300 actual lists. The sublist is one of those 300 lists. The superlist and sublist each contain the following keyword: * Auto-Delete= Yes,Full-Auto,Delay(1),Max(0),Probe(1) We had reason to publish to both the superlist and the sublist within the last 24 hours. The superlist monitoring report listed 85 errors, none of which were Probe failed. The sublist monitoring report listed 58 errors, every single one of which was a Probe failed. There was no crossover of errors between the two monitoring reports. My questions are: Why didn't the superlist monitoring report reflect the same Probe failed messages that the sublist monitoring report did? Do superlists actually have the ability to probe the addresses subscribed to the sublists? Should my settings be an different between a superlist and a sublist? Thanks for any assistance.
