Urgent - Spam-boat trying to break in the server

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]

Dear Falko

I found the below code in the link given by you

Code:

route add -host 62.58.60.226 reject

I am still troubling you.
where I should put that code.
and can I add multiple ip's

Thanks.

 

On the command line.

Run the command once for each IP.
