We need a better email broadcast/forwarding server

In case you haven't noticed, our ntuee80 account is now forwarding a list of detected spam messages to us each day.    I believe none of us want to see it yet I haven't figured out a way to stop it.     I tried to have the account forward the emails only to my yahoo account,  and then I can manually filter out the garbage and  forward useful messages to you.    It would be ok except that yahoo email has a limit on recipients.  

We may need to set up a yahoo group or google group.   They may have a limit on the group size too.   Does anybody know a better way?   Any suggestions?  Volunteers?
