ってメッセージで戻ってきます、仕方ないので携帯などからも送ってみたのですが

Your message was not delivered because the destination computer refused to accept it (the error message is reproduced below).
This type of error is usually due to a mis-configured account or mail delivery system on the destination computer;
however, it could be caused by your message since some mail systems refuse messages with invalid header information, or if they are too large.
