Delivery location per incoming domain?

[scanjam]

Can you divert all incoming emails from a particular domain to a particular bunch of users to a public folder.

all emails form users@domain1.com sent to users@domain2.com are all stored in a public folder thats accessible to all users@domain2.com?

basically like a centralised location, per client.

Or is it just as easy to have all recipients set a "reply to" address and set rules to move the incoming for that "replt to" mail box?

dunno if im even making sense now?
hope someone can work out my cryptic message..

cheers
