suppose there is an domain xyz.com accepting mails for its
user
say there are a, b and c users and administrator which will
recieve mails for unresolve members

i am sending one mail at dummy@xyz.com. dummy is not valid
mailbox still the mesg will be delivered to administrator of
xyz.com. so there will be not send fail exception.
