I never use water in the mix. Always dry. Never a problem with fence post etc.. Would not do it this way with a big project like a deck or larger fence. If you keep a bag of mix in a damp garage it will harden like a rock in the bag.
Mailbox post I use pea gravel. When a car or truck knocks it off and bust the 4x4 I can just dig out the gravel and replace. Very easy and no need to dig a new hole.
