moderated Email list

Technotronic Dimensions

Trying to get an integration going from one of the YAHOO groups just for the email list aspect. I dded the integration
email addres to the group member list, so the emails coming in to the system come in ok from the other
group, but for purposes of allowing the people on the system to reply and have it post, whats the best way?

I am a moderator of the YAHOO group so its easy to add in new emails to the system. I also can maybe use my email address
I am subscribed with as a way to make a filter or a forward, but not sure about the best way to do it.
