Hey!

Here are a bunch of ideas I thought about to compliment survival mode:

1. It would be nice if there is opportunity to have a cost like making payments to send mail, if not, then requiring players to put whatever they need to send in a package before sending out (which allows modpacks to then assign a price for the package). Creating packages would basically solve the issue where sending mail basically creates infinite bundles (players currently can put a bunch of items and send it to their own mail and take the package with them to save on inventory space for free).

2. To prevent players from using the mail service as an way to juke the dangers of being underground it would be nice if we can sit a Y level limit to where a mailbox can be set. It would be nice if we can set a limit to how far we can send packages.
