If you are running a mail server on IPv6, you really do not want to share the 
/64 with anyone else.
Everyone I know who does IPv6 address reputation aggregates by /64 since it it 
trivial for hosts to
hop around within the /64.  It would not be hard to use a different address for 
every message.  It's
not like you're going to run out.
