iRedMail Customization - Disable Greylisiting & Blacklisting

The following are the steps for disable the greylisitng and blacklsiting for iRedMail

Step1: Edit the policyd.conf

Policyd.conf controls the policyd setting.

vi /etc/postfix-policyd.conf

Step2: Turn off Blacklisitng and Greylisting

Find the word BLACKLISTING=1 and GREYLISTING=1. We need to turn it off by changing 1 to 0

#####################################################################
# BLACKLISTING (functional) #
#####################################################################
#
# blacklisting: default: off
#
# this enables blacklisting of ip/netblocks. this is needed
# if you want to allow any of the blacklisting features and
# the spamtrapping module. if blacklisting is disabled,
# the other modules still run and insert blacklisting records
# into the table, but it doesn't take effect untill you
# actually turn blacklisting on. this allows people to look
# and what hosts get blacklisted and see if any possible
# problems occured. (false-positive)
#
# 1=on 0=off
BLACKLISTING=0
GREYLISTING=0

Step3: Restart Services

Last step is to restart the policyd services, so that the policyd will take effect.

/etc/init.d/postfix-policyd restart
