For outgoing, at least for a mailserver, it does matter a lot which address is being used. Using the random address would mean the receiving server would have no way of identifying the sending server.
If using dhclient6 actually means not getting a random address assigned, that's probably what I need to do.

The first thing e.g. postfix does is do a reverse lookup of the IP of an inbound connection. Then it does a forward lookup.
V6 offers some privacy by using random numbers instead of fixed mac-addresses. One of the nicest things about v6 is, that you can add a lot of multiple addresses to you NIC.
