how can i prevent be flooded by config server (CSF) emails that notiffy about blocked IPs trying to connect server SSH?

// update:
i think it can be done only by disabling following in /etc/csf/csf.conf

 Send an email alert if an IP address is blocked by one of the [*] triggers

(setting to 0) and restarting csf and lfd ?

But it disable ALL login failure block emails for all services like FTP, SMTP, POP3, IMAP..

the "[*] triggers" is example this one:

# [*]Enable login failure detection of sshd connections#
# SECURITY NOTE: This option is affected by the RESTRICT_SYSLOG option. Read
# this file about RESTRICT_SYSLOG before enabling this option:
LF_SSHD = "5"
