If Postfix is the MX, it can relay to your IMail server. I think user
transport maps could be used to deliver only particular users to IMail. To
mirror all users, you can bcc to IMail.
Have you gone to postfix.org? The postfix-users list is probably the best
place to ask this.
imho- I wouldn't think waste of bandwidth/storage would be a great concern- but
opening up an administrative nightmare of what user is on what server would be
the biggest concern!:-)
