Yes, RFC 1597 :-)
Indirect references to such addresses should be contained
within the enterprise. Prominent examples of such
references are DNS Resource Records and other information
referring to internal private addresses.
That said, it wouldn't surprise me if there is someone somewhere using:
luser.com. IN MX 10 firewall.luser.com.
IN MX 20 internal-mailhost.luser.com.
internal-mailhost IN A 192.168.10.2
The following is an attached File item from cc:Mail. It contains
eight bit information which had to be encoded to insure successful trans-
mission through various mail systems. To decode the file use the UUDECODE
program.
