  It sounds like you want to log the user account in the deny list record comment. I don't know how to do that. If you just want to find out which account name was used to add an ip to the block list then do this... Go to Home " Plugins " ConfigServer Security & Firewall Choose "Watch System Logs" Choose "var/log.exim_rejectlog" Do a browser search for the blocked ip Use Shift + F3 to progress through the authentication failures for that ip Decide whether to remove the ip from the deny list or let it remain FYI. MS Outlook will make more than 10 failed authentication attempts if the client uses Outlook's Autodetect when setting up the account. (even with correct username/password)

  Hello, You may also want to consider using cPHulk instead of CSF/LFD for brute force protection purposes: cPHulk Brute Force Protection - Version 70 Documentation - cPanel Documentation Thank you.
