& mail()
 
  Syntax: mail(<mail message #>)
  Syntax: mail(<player name>)
  Syntax: mail(<player>, <mail message #>)
  Syntax: mail()
 
  The first form returns a message corresponding to that mail message 
  number in your MUX mailbox. This function can be used to forward 
  mail, or as a way to simply transfer mail messages to attributes on 
  an object.
 
  The second form returns three numbers, corresponding to the number 
  of read, unread, and cleared messages <player> has. The third form 
  returns <player>'s <mail message #>. It works like the first form 
  except it applies to another player. The last form returns the 
  number of messages the evaluating player has. Only wizards can use 
  the second and third forms of the function on other players.
