I'm trying to setup and test fail2ban with dovecot
I've installed fail2ban, I've copied config from https://wiki2.dovecot.org/HowTo/Fail2Ban, and, trying to test it,
attempted multiple mail access with wrong password, but, get this:
# fail2ban-client status dovecot-pop3imap
Status for the jail: dovecot-pop3imap
|- Filter
