There's not a nice function like that which can be used at that point, I 
don't think.

Try the attached patch.  It causes the DCN signal to be sent instead of 
RTN, and that should cause the sender to hang up or send DCN in reply, 
and the received but poor-quality page will get saved by virtue of 
SaveUnconfirmedPages... I hope.
