Putting in a new Cedar post. I like the idea someone mentioned about putting
stone ballast (pointy 1" to 2" stones) around the post, as these will lock into
place and stay relatively put over time (tamp them down as you fill the hole).
A big advantage of this is to allow drainage away from the post (make sure to
put 4" to 6" of ballast under the post bottom as well). So that's a good reason
not to use cement, which will stay moist over time and promote rot. No matter
what, a wood post will eventually rot, so having to dig out a cement plug each
time is going to be way more difficult than just pulling the post from the
stones and then scooping them out.
Make sure to use Coppercoat for the underground portion of a wood post,
especially a Cedar one. Place the post in a bucket and fill with Coppercoat to
soak the post bottom for hours (its weakest spot for rot). For Cedar posts,
apply Teak or Tung oil every few years for the above ground part (just slop it
on thick with a brush or cloth and let it soak in), maintaining a nice look as
well as preventing rot. Pressure treated wood will likely last longer than
untreated Cedar, but it will need to be treated regularly as well to prevent
cracking and warping (and moss buildup in damp locations). Personally, my wife
and I like the look of Teak oiled Cedar better than pressure treated wood, so
hopefully doing all of these things will give us a Cedar post that lasts a
decade or so.

I wouldnt use a wood post underground, better a metal post.
or whats now being used for deck footers. all conrete underground, with a heavy steel galvanized bracket attached to the top of the concrete post. wood post goes on top.
I got ticked at kids taking out my moms mailbox, so I replaced the light metal post with a heavy steel I beam, my best friend tried to get me to concrete it in I refused, and was glad later when that mailbox had to be relocated.
in any case I avoid concrete since if the post tilts, it can be straightened

Install one of these deck post sleeves in the ground.
Then when a drunken speeding teenage texter drives over your mailbox, you can quickly and easily install a new one.

Since my post above using gravel and Coppercoat, have rethought the whole thing.
What seems like the PERFECT solution is using the "SuperPost" sleeves
(available at Amazon or the company's removablepost.com website), which are hard
plastic sleeves that completely envelop the underground portion of a wood post
(including the bottom). These sleeves are permanently set in the ground using
either concrete or gravel, but the wood post is REMOVABLE. To replace a damaged
wood post, simply slide out the old one and slide in the new. There is a square
rubber gasket and cover that goes around the post to provide a watertight seal,
preventing water from getting inside the sleeve (these slide up a new post
during installation, and then are slid back down to seal against the sleeve once
the post is set inside). So the entire underground portion of the wood post
remains dry and free from ground contact (the top of the sleeve comes out of the
ground a little, which is why the rubber gasket has a brown or white decorative
cover). These sleeves come in 18, 24, and 36 inch lengths for 4 x 4 posts, and
36 inches for 5 x 5 (I think they are coming out with 6 x 6 sleeves too).
Feel free then to use a nice Cedar post for a mailbox, which when Teak or Tung
oiled above ground (every few years) should last for a decade or two (before
putting it in the ground, oil the underground sleeved part along with the rest,
just cause it's easy then and will provide extra protection). Even for
untreated Cedar fence posts though, there should not be any underground rotting.
What are you talking about? The post fits against a 24 inch sleeve on all
sides, with the sleeve buried in cement, so it should hardly move at all. For
severe rigidity, self-adhesive spacer tape can easily be put on two sides of the
wood post (prior to oiling/treatment) to make it really snug.
Hallerb, this is the second time you have criticized my posts with poorly
thought out responses (this thread is about how to minimize rot when using wood
posts, not about using metal posts or illegal I-beams ). Do not troll me again.

If a vehicle pushes against any post, wood steel I beam etc, it can be pushed out of PLUMB.
If its concreted in it will have to be completely dug up, removed then reinstalled and concreted again.
if its just placed in the ground and backfilled you can dig around it a bit, get it plumb, and backfill a fraction of the work.
ideally no one should use a wood post, since sooner or later it will rot.
now I have been posting here for perhaps 20 years, if you dont like my advice then ignore me or refute what I post. I REALLY DONT CARE!
The best advice I have got in many years was when purchasing my pole light. over 30 years ago, the salesman said dont conrete it in, so you can easily straihten it if needed......
well its been pushed over by a mailman falling on the sidewalk, been pushed at when a out of control car left he road and hit it, its had several unfortunate events, its gotten a few bumps but is very easy to make it straight again
get it plumb, and backfill a fraction of the work.

Advice is one thing, mindless criticism is another. That was why it was hard to
ignore you, which I will certainly do in the future. Signing off.

with pressure treated wood placing it in a concrete base will help to prevent
rot.. being pressure treated it is less porous on the sides but the top and
bottom will have been cut from a larger log and so will not have the pressure
treatment so it it wise to seal for longer life.. if you are using a soft or
more porous wood then it will LIKELY act as a pool and not allow local shrubs to
absorb the moisture like they do in soil
