I am running Listserv 1.8e on a Windows 2000 server sending mail via the L-Soft LSMTP. I am housing 50+ lists on the server. For some reason posts to one list in particular do not get distributed. Posts to "abclist" make it to the list because they show up in the archives, and the log lists that the mail gets distributed, but they do not get sent out. I know because a subscriber and I sent a post twice to this list of 600+ and did not get a single out-of-office reply, nor a confirmation that the post was received, and neither of us received the post in our in-box. Our subscriptions are set to MAIL. I've tried re-starting the Listserv server, and reloading the list header, freeing the list, but to no avail. The other lists seem to be working fine. We began implementing Spamcop on our Exchange mail server about the same time this began happening but since have disabled it, but it did not help. Any suggestions? Keach Sasamori IPC IS Administrator
