How to change ip mail server?

Greetings community of centos web panel,

unfortunately my main ip got on the list of blocked by Microsoft, (hotmail.com, msn.com, live.com etc ..) due to spam, I would need to change the ip address of my mail server, unfortunately I don't know exactly how to do it and I would need instructions. That is why I am asking your community for advice.

Thank you all.

you should resolve the spamming issue on the server and not by changing the IP.
The spammer can be easily found using logs also there are several instructions and commands on the cwp wiki.

for IP change of postfix you need to check the postfix config/instructions

The problem was solved, we were asked by Microsoft via https://support.microsoft.com/cs-cz/supportrequestform/8ad563e3-288e-2a61-8122-3ba03d6b8d75 to remove the our ip from the blacklist, the reason for adding it to the blacklist: was Blocked due to user complaints or other evidence of spamming.

After checking the logs, we did not find any spam boots or anything like that.
