If this is an Exchange-based distribution list, there is often an e-mail alias associated with the group. Check the Outlook properties for the group alias.

If it's just an e-mail contact list from your personal address book, then I think the answer is No -- you can get SAS to send e-mail directly to that, especially when using SMTP. You would have to export the list and read that into a SAS macro/variable to build the dist list for use in SAS.
