Hello all, This is probably a query which should have gone direct to LSoft support, but I thought I'd air it here out of potential interest to other users. We have recently imported several lists from another organisation, one of the lists was called owner-talk. Initially I did not suspect a problem with this list, but it rapidly came to light that mails to the list were falling into a black hole, no response, no error returned, not logged anywhere. I guessed finally that the machine was actually looking for the owner of the list talk which did not exist. What I wanted to ask was why there was no error report generated, when someone mailed to owner-talk why did they not receive an error saying that the list talk did not exist, or that no owner of that list could be found ? We have subsequently renamed the list owners-talk and it works fine, but the strange behaviour was slightly worrying, since we did not know there was a problem at first. Thanks for any pointers Duncan Russell
