[exim] OT: dead user

Off topic, but i think someone could help me:
an user in my domain passed away yesteday.
What is the best way to cope with it.
she used her personal office e-mail address to receive correpondence for
all the group, so forwarding to her substitute would expose to a leak of
personal correspondence, setting an autoresponder saying the
addressee is dead and office correspondence should be sent to a new
address could lead to people not resending the message to he correct
address.
what to do ?
