Is there a configuration setting in Listserv that will prevent subscribers from selecting "reply-all" in their mail client and responding to everyone on the list? The configuration Reply-to= Sender, Respect does not prevent a subscriber from selecting the Reply-All button in their mail client. What this configuration does is place the original sender's address in the "to" field when a user hits reply. This differs from Reply-to= List, Respect because this setting would place the list address in the "to" field when a user selects reply. But, If a user actually selects "Reply All" in their mail client it will send to both the list & the original sender. Olubanke O. Awofeso
