Is there any configuration about IP Rate Limit?

[Cnily03]

Early this day, I received an email said he has hacked my email account. The logs show that he had been attacking for months and finally bruted the email password. I wonder if maddy provides a configuration about IP rate limit in authentication process.

maddy offers no built-in protection, however you can easily configure fail2ban to ban ips that attempt bruteforcing.
