Hi Federico,

Thunderbird is an example: if I choose Reply it replies just to the sender, if I choose Reply all it replies to the sender and cc the list (just like in this email). But I've found out right now this addon (Reply to mailing list): https://addons.mozilla.org/en-US/thunderbird/addon/4455
I think an important tool for mailing list handling is the Mail-Followup-To header[1].
According to this site[2] Thunderbird (at least since version 3) should be able to handle this header. So it should be one of the really rare mail clients which can handle mailing lists follow ups automatically and intelligent.
