Hello Ladies and Gents, My current setup is as follows: Windows 2000 server Listserv v1.8d Exchange 5.5 front end (mailer instead of LSMTP) Here is the problem. When there is a service interruption, such as DNS stops(which causes Exchange to stop sending mail) or our ISP disconnects.. ect, mail from the list is obvious affected and cut off. The real problem comes in when service is restored, though. Messages that have already been disseminated to the list will start sending to all of the list users. It seems that the longer it is offline, the more messages (and older... usually no more than a day or 2) are sent out. I cannot find where they are being stored at either... neither Exchange nor listserv shows these messages until the service is reconnected.... Any suggestions? I have pretty much come to the point where I am about to give up and take it for granted that it is going to do this every time service is interrupted. This is driving what little sanity I have away... =-) Thanks in advance... Michael Reed Municipal Code Corporation There coming to take me away, haha. There coming to take me away, hoho.
