Is there a way to send out messages to a yahoo group that don't allow any replies.?

I am the moderator of a brand new yahoo group with several hundred members. We have members accidentally replying to the entire group when it is not appropriate. At a minimum I need to eliminate the ability to reply to the entire group. I cannot figure out how to do this in the management settings. If I change posting options to "moderated" will all replies to messages go through me as the moderator so I can stop them?
