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
: <[🔎] Pine.BSI.3.95.980308195613.20968A-100000@ns1.midco.net>. I guess BSI
: means BSDI ? Just my 2c about hiding the OS.
Point taken.
