First, perform the lookup by ID/Status or Group. Then click Lookup | E-mail. Click on the drop-down in the middle that says "Starts With" and change it to "Contains Data". In the drop-down labeled For the current lookup: where it says "Replace Lookup", change that to "Narrow Lookup". Then click OK and you'll have a look up of your ID/Status or Group contacts that have *something* in the e-mail field.
Hope that helps -
