When there is a problem with e-mail delivery, never assume it is on your server. Look at error codes and logs. In this case, the receiving server returned a code of 4.2.1 indicating an issue on their end. There is = nothing you can do about it. Your server will requeue the message and retry = later until one of 3 things happen: It transmits the message completely, it = gets a error code of 5.x.x and then deletes the message, or the number of = retries is exceeded and deletes the message and sends the postmaster notice.
