Add to Server-Wide Black List and White List block by IP adress and DOMAIN name.
Server-Wide Black List blocking only by domain name is insufficient, because spammers can spoof real sender adress. Not every sender has SPF record configured. And also email White List needs whitelist by domain name to block common spammers with no fixed IP.

very annoying, cant block mail by ip.
plesk is hogging the postfix blacklist file and for no reason doesnt allow ips to be entered.
just fix the stupid sanity check. -

Some years later, this problem still exits. You cannot add an IP address, nor can you add a domain. It doesn't accept it?

serverwide mail setting we can only add ip in whitelist not domain name
at user level we can add domain in individual domain settings -

As of now Tools & Settings => Mail Server Settings => Blacklist we can only add domain name but can't add IP addres. Where as in white list we can add IP address but not domain names
Actulally in both we should be able to add IP address as well as domain name
If there is hugh traffic coming from particular IP address then then admin need to block IP address. Also if sender is genuine and admin want to whitelist particular domain in white there should be option
Keeping only one option in whitelist and black list does not solve purpose fully
