auto sorting mail clients

[chadi]

Hi !
   im looking for a good email client (graphical and non-graphical) w/c can 
automatically sort out emails like put all mails where either the to: or the 
cc: fields contain debian-user@lists.debian.org etc etc.  seems like there are 
just too many of them to try out one by one.
   can anyone suggest something to me and maybe tell me in a few lines why they 
prefer that client ?
TIA,
chad
