I have already blacklisted the below
IP 122.1116.133.64 in Global-Filter-Postfix-Blacklist, but this IP is constantly trying to connect to my server.
I am getting this IP in my logs repeatedly.
What else can I do to block this IP to even contact with my server.
Code:
Aug 16 02:40:19 server1 postfix/smtpd[20384]: connect from 122-116-113-64.HINET-IP.hinet.net[122.116.113.64]
