Index of Subjects Hello, unfortunately I had never received the root@cobequidnet.ns.ca message as someone else apparently has the root account's mail forwarded to his mailbox. Thanks for reposting it Michael and thanks for the follow up on it Don Mackill. I made the changes and we will just have to see if it fixes the problem, so far it is good but of course this is just about 5 minutes after the first test message. I hope that I don't see this for another 20 or so times. ;-) Dave On Thu, 1 Jul 1999, Michael Smith wrote: > <cranky=off> (ok, now I've got some sleep behind me ;) > > On Thu, 1 Jul 1999 don.mackill@iname.com wrote: > > > Dave Wile forwarded a message to me subjected, "How zmailer does its > > thing..." that he received from you in response to his question.
