Don't set posts in concrete. A mailbox post will do quite well in
compacted dirt/crushed rock.

Concrete will keep to post moist and cause premature rot. It'll also
make replacement a PIA.

Just set the post on a bed of crushed rock and backfill with a blend
of dirt and rock. Dome the top and tamp it in well.
I agree. I think the reason the fence companies use concrete is that
tamping is a lot of work and it is faster and easier to set a post in
concrete. They never take out the old ones either. They just cut them off.
