I have run nessus against a remote machine, and it has discovered that the server is running postfix 1.1.11. Nessus has fingerprinted the server through smtpscan (plugin 11421). The question is: is there a way to avoid being fingerprinted in Postfix? Thanks in advance for your answers, Regardes Isidro Labrador Rodr?guez
See postconf(5), under smtpd_banner. (I'm pretty sure Nessus just grabs
the banner; however, some more advanced fingerprinting is possible, if
someone is very knowledgeable.)
