My understanding of this is that it cannot be done be default, but anything can be done by altering the resend scripts to accomodate. You would need make a call to sendmail for every person in the recipient list and remove the DL as the original recipient. This may be more work than you want to sign up for.
If anyone knows an easy way... I too would like to know.

I would create a "list file" with only those three individuals and set your restrict post to that list file. Delivery would occur to the entire list, but only those three would be able to post.
For the To: field question... are you asking that the sender address show up in the TO: field, or the individual recipient such that each person receiving the message will see his/her address in the To field?
Wether or not you can put the individual recipient in the To field for each person recieving the message. So the message looks like to came from Me, to just you.
