How To change IP in server

*Note:- Hey Remember < You need to set RDNS for the IP then and then Only you can proceed further.>
-------------------------------------------------------------------------------------
If you are in the danger of getting your main server IP block by SpamCop because you had a few anoying spamers abusing your server, then you could simply change your exim mailserver IP to avoid the effect of your main IP beeing blacklisted.

--Below there are some simple steps of changing your exim IP:---

Inside both incoming & outgoing exim mail server you will need to add an interface :-
( So just edit )

pico /etc/exim_outgoing.conf

and

pico /etc/exim.conf

find
remote_smtp:
driver = smtp

& add interface = ip.you.want.to.use

--------------------------------
Example is as shown below:-

remote_smtp:
driver = smtp
interface = 22.22.22.22
-------------------------------

IP needs to be on server in order for this to work, hopefully this will help.
BTW: Just a reminder - If there is an exim update when you upgrade your cpanel server you will need to re-enter the interface again.
