Say for instance you have some one trying to constantly access an account
Has any of you made something creative like this:
- configure that account to allow to login with any password
- link that account to something like /dev/zero that generates infinite amount of messages (maybe send an archive of virusses?)
- transferring TB's of data to this harassing client.
I think it would be interesting to be able to do such a thing.
As long as you have infinite bandwidth, that may be fun, but it is not the case for most people operating a mail server I think.
For theses clients, I simply have fail2ban and DROP packages of blocked IP (I prefer to DROP because I don't want to waste resources responding that the connection is refused).
