"Enable native brute-force protection module for Dovecot to protect against IMAP/POP3 services attacks"

Enable:

imunify360-agent config update '{"PAM": {"exim_dovecot_native": true}}'

Disable (default state):

imunify360-agent config update '{"PAM": {"exim_dovecot_native": false}}'

The notification will disappear after a while, as these warnings are updated once a day.
