You missed the point :) - I was asking about ssltelnet's habit of throwing a zillion headers at you before the login prompt ... : BTW: if you "telnet localhost smtp", you can see the version and brand of : your MTA. Another info for intruders. Even if you disable this: the output : of the smtp "help" command will help in identifing the MTA anyway (as it : is distinct on the different MTAs). You can even see the OS and MTA in any : mail sent. Check the headers of this mail. You will find the string (Debian : Smail3.2.0.100). Yes, and ftp daemons, etc ... : On your mail, I can also see using the message-id : <[EMAIL PROTECTED]>. I guess BSI : means BSDI ? Just my 2c about hiding the OS.
