When document is submitted via OfficeMail Web submission overflow pages are created.
Document has more content that can fit into A4 page without page breaks, resulting to overflow pages in the Web submission client.
This is not flagged as an error in the Web Submission client as the Web Submission only checks the reserved areas, margins do not qualify for this.
If the margins were flagged as reserved areas that would prevent customers using headers and footers in the documents.
Documents should be created in such a fashion that there are clear page breaks which decide when to create next page.
