Protect your IBM Lotus Domino Server against brute force attacks on non HTTP ports

Chris Brandlehner provides excellent advise how to harden a Domino server further against dictionary attacks. Of course you only need that if you allow non-Notes clients to authenticate via SMTP. If that's off (as in good Notes/iNotes only shops), you don't need to protect that vector. Anyhow the script is designed for Linux, I guess it works on AIX, Solaris and other Unix too. I wonder what you do on Windows.
