(non-working) email commands

[insomniac]

I really, really, want in-game e-mail. I am desperate, it's sad..
we know its functional (see: petition system) and while making the /list i could help but notice all the email commands... and play with them

cancel_mail
deletemailmessage
getmailmessage
getmailheaders
start_mail
sendmail

anything other than /start_mail gets you "You are currently not in a mail transaction"
/start_mail will actually get you something semi useful: "[DEVL]Usage: start_mail < mailbox_id >."
/start_mail shizlak? nope. same message..
/start_mail [bunch of numbers]? yep!
"You do not have a valid mailbox target."

so what does that mean? vaild mailbox target? wrong set of numbers? (i tried my station player id, no luck)

Does it mean.. like.. target window "target"? or location? i tired in the feild at first, then i tried next to the banker, innkeeper, in my house, nothing.

I want email!!! /cry
