TO BE CONTINUED, DO NOT APPLY THEM.

iRedMail ships Policyd-1.8.x for sender & recipient throttling, but it's disabled by default. You can enable it by follow below steps on RHEL/CentOS:

  • Enable throttling in /etc/postfix-policyd.conf:
File: /etc/policyd.conf 
SENDERTHROTTLE=1
SENDER_THROTTLE_SASL=0
SENDER_THROTTLE_HOST=1

RECIPIENTTHROTTLE=1
  • Restart policyd service:
Terminal: 
# /etc/init.d/policyd restart

It will listen on two ports: 10031, 10032. You can verify it via command netstat:

Terminal: 
# netstat -ntlp | grep -i 10031
tcp        0      0 127.0.0.1:10031             0.0.0.0:*                   LISTEN      3454/policyd
  • Enable throttling in Postfix /etc/postfix/main.cf:
File: /etc/postfix/main.cf 
smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:10031

Restart postfix:

Terminal: 
# /etc/init.d/postfix restart

That's all. Enjoy. :)
