To my knowledge this cannot be done using an "Exchange client" However, if you have IMAP service running, then this is possible using IMAP clients as they can be configured for different "reply to" address. It will also depend upon your outgoing server as to weather a unique "reply-to" address will be overwritten when sending.
I am not a big fan of doing this so my suggestion is to create a 'shared/resource mailbox' so that these addresses can be kept distinct and use "Send-As" access. This will work better, just as long as "Sent items" for 'project mailbox' don't need to be kept in that mailbox.

I added an address to his properties so he could receive mail sent to [email protected]<mailto:[email protected]>. Project doesn't have a separate mailbox, it's mail just gets delivered to Joes's address and joe has a rule that redirects project mail to a specific folder. Now, Joe would like to send mail as [email protected]<mailto:[email protected]> so mail comes from the project instead of him. Is it possible to do a send as when project doesn't have a mailbox? Thanks for your help.
