The smtp command is
FORGEFROMHOST <forged hostname>
the mail server will then send a challenge using KERBEROS to verify that
you are, indeed, forging your hostname. If you are not forging your
hostname, the server will close the connection. Most servers will log
this activity as a security hazard, so don't give it your real hostname.
This is only true for servers that don't have data striped disks. If
they do have data striped disks, then you must issue the command
FORGEFROMHOST <forged hostname> 0xdf
The server will then send a username from its /etc/passwd file along
with the unencrypted password. You must reencrypt this password for
extra security and reissue it back to the server. If the RST flag in the
tcp packet from the server is set, than this must be done quickly.
