ShowMailBox is empty

[ataraxyaffliction]

Calling ShowMainBox opens an empty mail window. But if you open mail through a mailbox or GM command, and call ShowMailBox, then the mail will be displayed.
I can’t understand what exactly is the problem, because the implementation of the request is essentially the same as that of GM command. Trinity core.

What is the guid you pass into ShowMailBox?
The guid is supposed to be a valid mailbox guid. Otherwise it will not work - except if you are a GM.
It seems that if you use creature guid it needs to have npcflag 0x04000000 set.
The requirements vary by core,

I think this code nicely outlines the main restrictions: https://github.com/TrinityCore/TrinityCore/blob/53cc21b1b45e11ba9358df3281cfa2b021fb1ea0/src/server/game/Handlers/MailHandler.cpp#L36-L60

The Eluna documentation says that you need to pass the player's ID. If i try to pass the Mailbox object ID, nothing happens. Is it possible to open a game object interaction (for example, a mailbox or a guild bank)? Unfortunately, I didn't find anything in the documentation.

Yes, if you grant rbac permission 777 for the account, then everything works. As I understand, there are two options - grant permission, or remove the check from the core.

Is the mailbox close enough? The mailbox must be within interaction distance.

Yeah, if mailbox close enough everything is working fine. But I wanted to use mail anywhere. I'll just add permission.
