This just means that you don't have a handler for the message type
involved -- since the message is returning, it is junked (otherwise
it would have been saved and mail sent to NCC_MANAGER

The bytes after the ROUTE string show the original route (before being
returned) as csaadel,lux,sirius,augean,munnari,goanna,munnari,goanna.

So it looks like goanna and munnari disagree about the route to wherever
it was originally destined. (As you seem to have truncated the error
message before the part with the destination address, it is hard to tell).

Anyway, as both munnari and goanna are running SUNIII, this is probably
one of the usual SUNIII routing bugs emerging. Contact the managers at
these sites with details of the original destination you were trying to
reach, and try persuading them to hack their routing tables to get around
the loop.
