Hey folks, please help

[Brandon Wolf]

This hopefully will be the right place to ask this question.  My ISP just changed to qmail and added the mailing list software to.  My question is, how can you change the mailing list so that the reply to address is always the list address?  I have had people complain about having to forward the mail back the list and reenter the list address vs hitting reply.  Any help would be greatly appreciated   THanks Brandon Wolf
