I think it would be divine if there was an option to controle from who you can receive mails ingame.(pretty much like how you can controle which channels you see in chat)
There might be a few exceptions,like messages from a gamemaster,bought and sold guildstore items will always be deliverd to the mailbox.(but for the rest any other unwanted inbox messages will be blocked away)
A few checkboxes for "who I want to receive ingame mails from:"
x Guildmembers
x friends
right click name in chat of player you want to bargain with:"grant temporary bargaining rights"..if you don't know the player but would like to trade.
Its not nice when you think you sold something on the guildstore,just to discover its another goldspam message
Perhaps any 'unwanted' messages that got sended and blocked from your inbox could pass the investigation team instead.
Or if they contain a few keywords like "gold" "k" "motif" "selling" "most trusted" "www.com"
