Scott,
What specifically is their application? Remember, the 2035/45, 1224/32, the 2090/2105, and 1060/75 all come with scan to e-mail out of the box. If they are sending to less than 2000 destinations, and don't require authentication. You're good to go out of the box. I'm told there is a way to create a csv? file form you e-mail address book and upload to the copier via smartnet monitor.
If they require authentication or direct access to mailserver then you add Global Scan.
