I know how it works, I also use it in some places. The concern that I
have is that most of the requests that my list receives come from very
few organizations. This leaves me with a very small number of client IP

If I block a particular IP address because some disgruntled person from
the organization is trying to brute force, it will block access for
other legitimate users from that organization (because they have only
one IP dedicated to browsing traffic). That is why I was looking for
something that can look at the username/email and block request or show
captcha if number of failed attempts cross a certain limit, at
application(mailman) level.

I think this is sounding more like a feature request.

Thanks & Regards
Aditya Jain
