How to permanently remove an ip-address from the blacklist on the site www.abuseat.org?

Question

Computer networks

Hello! Recently, mail has ceased to leave the local network. When you try to send, you get a message that the ip address is blocked on the site www.abuseat.org. On the site itself, they write about this:
his IP is infected with, or is NATting for a machine infected with Win32/Dorkbot
This was detected by observing this IP attempting to make contact to a Win32/Dorkbot Command and Control server, with contents unique to Win32/Dorkbot C&C command protocols.
Win32/Dorkbot is a worm, and can travel to infect other computers via Instant Messaging, Twitter, Facebook and even USB drives.
Once installed, it gets involved with clickfraud, and can act as "ransomware" - locking the user out of their computer or encrypting the contents until the user pays a "ransom".
This was detected by a TCP/IP connection from MY_IP on port 20389 going to IP address 192.42.116.41 (the sinkhole) on port 3720.
The botnet command and control domain for this connection was "n.hmiblgoja.ru".
Has anyone encountered this problem?
