Background Job & Spool List Recipient not receiving all pages

I have a program that is run during our nightly cycle and is scheduled in SM36 with a spool list recipient designated for the report to be delivered to the user's SAP Inbox. The job completes successfully and creates a report that is over 100 pages. The user is only receiving 10 pages in their SAP Inbox. Is this a Basis system setting? Can we changes this on a per user basis?

Thanks,

Holly
