looking for: mail list AND bulletin board in one

[Vadik <vadik@kutsyy.com>]

I am looking for package with capabilities similar to yahoogroups (i.e. 
mail list AND bulletin board).  Most of the packages I've seen are 
either maillists or bulletin board.  If this would be a part of larger  
content management system (or can be integrated in to one) it would be 
additional benefit.

Any recommendations?

Thanks.

PS: sorry, it is lightly OT.
