I would like to set up multiple email addresses on the same domain that are all viewable under one account.

The email addresses will be used by different people, however the main account will need to be able to see not only the received messages, but also the sent messages.

That is, I would like to be able to see what messages other people send and receive. The receiving part can easily be done by forwarding... However, I would like a way to see sent messages as well. Ideally, it will be some form of sync through IMAP.

Cheers,

Luke
