[Mailman-Users] reply to posting on web?

[Robert Vibert]

Hello,

I am looking for a mailing list which enables:

- some users to read and respond to all messages by email
- some to read messages on a web BB forum and be able to 
respond to specific messages via the web interface (their 
responses would be sent to the email group as well)

Does Mailman do this with Smartlist or Majordomo?

TIA

Robert
