I want better email SW. Can Evolution/Majordomo deliver?

[Piper]

Let me rephrase the issue which brought me to this list.

I want better email SW than Windows Express especially when it comes to the 
listserver aspect of Express Mailbox, ie

... a mailbox listerver which does more than allow x number of email 
addresses under a name like "ABC List".

I only need 2 additional features:

(1) When the email comes in here to ABC, a "reflector expression" will send 
it back out automatically to all others on ABC.

(2) When J Doe wants to sub/unsub for ABC, Doe can send a command here and 
it will be automatically processed accordingly.

Am I asking for too much?

If Evolution cannot be modified to do this, what about Majordomo on a Linux 
machine?

I DO NOT WANT TO BE A PUBLIC "SERVER". I want a PRIVATE listservice as 
above. That is not the business of any ISP. It is a legitimate user request. 
BTW it is not out of any deference to my ISP that I say this. I do not want 
the legal liability of "hosting" anybody else's list.
