Usermin webmail login blocked after too many attempts

SYSTEM INFORMATION
OS type and version debian 10 (buster)
Webmin version 2.00
Usermin version 1.860

I came across this late post about getting locked out of usermin.

[type or paste code here](https://forum.virtualmin.com/t/webmin-user-blocked/53279)

I encouraged some users to use usermin, and of course they locked themselves out. But before I saw the late post I assumed this was blocked with fail2ban using webmin-auth maybe. This wasn’t the case, and I can see that this was an internal function.

Wouldn’t it make more sense to do this with fail2ban? I mean restarting webmin seems cumbersome, specially if several users would be using usermin no?
