I want to restrict certain non-RFC compliant or otherwise chatty mail systems from bouncing mail to my list. If I add a subscription for the system and set it's options to nomail, will this prevent listserv from accepting posts from the mail system? =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Tom Cervenka - Univ of Il at Chicago, Info Cntr, Phone 6-7739 Internet: [log in to unmask]
