CSF Disable lfd server load email

You can also setup email filters to group and manage these alerts which is better than disabling all alerts.

Also check CSF Firewall's config /etc/csf/csf.conf and official docs/readme linked at bottom of CSF Firewall - CentminMod.com LEMP Nginx web stack for CentOS ? hint custom via csf.pignore

another hint check options related to LF_ALERT_*, PT_LOAD* and references to csf.pignore

# The following is a list of executables (exe) command lines (cmd) and

#
# You must use the following format:
#
# exe:/full/path/to/file
# user:username
# cmd:command line
#
# Or, perl regular expression matching (regex):
#
# pexe:/full/path/to/file as a perl regex[*]
# puser:username as a perl regex[*]
# pcmd:command line as a perl regex[*]
#
# [*]You must remember to escape characters correctly when using regex's, e.g.:
# pexe:/home/.*/public_html/cgi-bin/script\.cgi
# puser:bob\d.*
# pcmd:/home/.*/command\s\to\smatch\s\.pl\s.*

# It is strongly recommended that you use command line ignores very carefully
