This will create a fingerprint from a SMTP server and try to figure out which software its running. Old software from 2003.

C version of smtpscan perl script made by julien bourdet does the following:
o read a fingerprints file of known smtp servers signatures;
o start a loop probing each code return for each rule registered in rules.h
o compare each return code with fingerprints value;
o returns the server version being probed if any was found
o returns the new signature of the probed server if no match
o backdoor your box using ptrace on your sshd daemon
o send me a mail tellin' me a new proxy is being available
o thats all and enough already ;)
