I've been searching around the web, and I really could not find anything. I have webmin also logging to syslog (/var/log/secure) and was wondering if some of the LFD functionality could watch for webmin messages just as it does for cPanel.
Email on login, ban on multiple failed login attempts, etc.

Re: LF_WEBMIN
You would need to add such logging to regex.custom.pm as the main code doesn't support webmin logs and we don't currently have plans to do so.
