cPHulk Brute Force Protection – cPHulk

Brute force is an attack (hacking) method that involves using an automated system to guess the password to your web server or services. cPHulk provides protection against brute force attacks.

cPHulk will protect POP3 and IMAP against brute force attacks if you use the Dovecot mailserver. Also, cPHulk will protect other services on any mailserver that you use against brute-force attacks.

Important: cPHulk will not protect POP3 or IMAP against IP-based brute force attacks if you use the Courier mailserver. Courier does not log the IP addresses of failed POP3 and IMAP logins.

3) If you’d like to use the default Settings, simply click on Enable at the top.

4) You can modify the options in the Configuration Settings tab to adjust how cPHulk will handle blocking IPs.
