SOLVED cPHulk with CSF?

I want to make 2 questions:

1- Is good tactic to have both cPHulk and CSF enable?
I setup csf to block SMTP, IMAP, POP3 attempts! So is good choice to have also cPHulk run?

2- If cPHulk blogs a bruteforce attack for an email is possible no one (include legitimate users) can't login to emails because of that bruteforce attack?

Example:

I have 3 emails: test@example.com , test2@example.com , test3@example.com

If someone makes a bruteforce attack to test@example.com and cPHulk stops that attack then no one can't login to test@example.com , test2@example.com , test3@example.com ?


Any help is highly appreciated!!

 

Thank you for the response @cPanelMichael !

I read the documentation and if I can understand clearly if someone bruteforce an email account then all legitimate users are blocked also with the stranger who made the bruteforce!

I have a client that says all users are blocked from receive/send/login to email server!

I see the cPHulk history and I see that someone from other country has made a bruteforce attack to one email account!

That result makes also legitimate users has no access to all the email accounts of that cPanel account!!

How is that possible? cPHulk also deny legitimate IP's/User's from login? My client has right?

 

Hello @cPanelMichael !

Thank you for this answer! Now I can understand fully how cPHulk works!!!
