OL2003 - I would like to be able to create a distribution list based of
the multiple email addresses in the To: line on a recently received email.
There are about 25 names/addresses this email was sent to. It would be
nice not to have to enter them individually into a new blank D/L.

Any ideas?

Thanks.

Jack
