Vindictive correspondent scrapping second page (5)
I believe the answer is:
penal
'vindictive' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for penal that I've seen before include "Very severe" , "Involving legal punishment" , "Corrective" , "Punishing" , "Relating to legal punishment" .)
