How can I stop Pop3 Brute Force attacks

Hello people,

I'm pretty new with Linux, and have a mail server running RHEL, with postfix, dovecot, etc.

I installed Fail2ban and this works wonders against SSH brute force attacks. It'll ban an IP address for a period of time if it unsuccessfully attempts to log on 3 times within, say a minute.

I was wondering if it can be as effective with pop3 attacks. If it is, how can I get it done?

Thank you.

You need to create a regex, and add it to fail2ban
Here is a guide.

Kind regards
