I am on a list that is gatewayed to a newsgroup. People cannot post to the newsgroup without first being subscribed to the list. This means that anything posted to the newsgroup first goes to the Listserv, then back out to the newsgroup. Someone posted a message and forged my return address. Since I was a list subscriber the post went through. I'd like to cancel the newsgroup post. If I issue a cancel message from the newsgroup it will go to the Listserv first. Will the Listserv pass it through and back to the newsgroup? Will the Listserv also post it to the list, or is it smart enough to realize it is a cancel and not post to the list? Thanks, Don.
