Untested but the top space could be added by using $template_hook[postbit_messagearea_start] in the vB postbit_legacy template, or after $template_hook[postbit_messagearea_start] in that template add in the following:

<div style="width:100%; padding:$stylevar[cellpadding]px;" align="$stylevar[left]">
	text in top space
</div>

Again untested but the bottom space could be added by using $template_hook[postbit_controls] in the vB postbit_legacy template, or after $template_hook[postbit_controls] in that template add in the following:

<div style="width:100%; padding:$stylevar[cellpadding]px;" align="$stylevar[left]">
	text in bottom space
</div>
