+Connecting back to our servers through the tunnel does not require actions beyond what is described above. If, however, it should be necessary to use the sub-delegated addresses as source address for sending mail, further action is required.

Details of the name space delegation is described in [[cross-allocation|IPv6 Cross allocation]]
