I have a dedicated server, one of my customers trying to sent spam and I suspended his account.
but my ip blocked on internet and my customers cannot send their emails, how can I unblocking my server IP ?

You will have to apply for delisting of your email server IP address using the information you receive in the bounce back from the remote email servers.
In some cases, you will not find a URL/web link for delisting. In that case, the issue is usually resolved automatically after the blocking list database removes your IP in a period of 24 - 72 hours.
Which MTA are you using btw ? In Exim you can also change the outgoing interface IP address so that all emails route through that IP. The IP address of the email server needs to have a rDNS(Reverse DNS) set.

http://www.spamhaus.org/.
Also maintain the following for you mail servers 1) SPF record 2) Proper reverse DNS 3) Submit mail sending request with you list of IP address to MSM/hotmail , AOL etc.

I checked my IP on cbl.abuseat.org , in this site said :
IP Address x.x.x.x is not currently listed in the CBL.

Check with your DC / ISP to make a reverse dns entry for you. this is the first requirement for you. Then SPF..
