Reynard said:Considering the average trader/freighter sticks to safe routes and don't stray too far from the 100D limit AND there are only two pirate encounters of sixty possible encounters on a 16% chance for encounters, I'd say people see very little reason to buy a lot of insurance if they get any at all. Happens in real life until something that one time goes wrong. Highly valued cargos might expect the shipper to be bonded or there be a contract of insurance between the two entities. At some point, someone is going to be responsible.

If mail is electronic, it probably erases itself, either through detection of unauthorized tempering and/or the captain frying the memory transistors.
Packages delivery and physical letters would need insurance, or should be insured. The insurance company determines if the mailship has to be armed, and how safe the mail run is.
