save mass-mailing reciipeints' email address

[L.J.]

I recieved a mass-forwarded email, and I need to copy down the email
addresses of all receipients of that email (in the To field of that email).
In essence I need to create a contact list devoted entirely to those
receipient. Is there an easier way to do this other than clicking on each
name individually and adding them?

I seem to recall some way of creating a folder with all these names,
exporting it to excel, and then importing it into contacts. Is this
possible?

Thanks in advance!
