Basically it reads "From the point of view of cmcl2.NYU.EDU, the return address is ccnysci!... It is quite legal on the Internet, although UUCP sites shouldn't see these beasts. Also, this one seems a bit peculiar in that [1] cmcl2 is mentioned both in the source and the route, and [2] your host is mentioned twice. It looks like someone blew it in the cf file. For more information on route-addrs I refer you to RFC822.
