Mog mail for alts.

First off let me say that not sure if this is the correct place to put it if it's not can someone move it to where it belongs thank you. I currently play on two different characters on the same server. We currently have cross realm partner finders and some cross world linkshells. Will the game ever allow us to be able to send mail to alt on the same account? For me personally it's kinda tedious to have to ask a friend to hold something so I can have it switched from one character to another. I guess what I'm asking is if it's even possible to have something where we can send mail to ourselves on alt accounts or if it's not really applicable. Thank you
