Where is that message coming from? From the remote sites? From the
telnet client? From some device in the network path, e.g. a firewall?

If I had to guess, I'd say that the remote sites are complaining about
the lack of reverse mapping for the address from which they see the
telnet requests originating, whether that be a "real" address, a NAT'ed
address, a telnet proxy address, or whatever. Do you have the
appropriate PTR records in place and visible to the Internet?
