A delivery system capable of sending mail for free to alleviate the burden of a connecting fee on the mail receiver. A sender of free mail for reducing the burden of a receive connecting fee for the sent mail is registered in the server, and acquires an ID from the server. When sending mail, the registered sender of the free mail selects whether or not to bear (pay) the cost of the receive connection fee, or whether or not to pay a royalty to the mail receiver. The cellular telephone of the mail receiver displays whether or not the connection fee is free, and displays the amount if there is a royalty. The server bills the mail sender for the receive connection fee. Mail may also be automatically received when receiving free mail with no connection fee.
