It is not userful or more clear for me.

What is it you are after?
If you want to avoid/prevent users from accessing their email outside the office, disable external access to the website.
There are many log crunchers that you can run on the apache web site.
If you want to stop people from entering, lock the door. While you have to allow external system access to the SMTP port to deliver a message, it is not a requirement to open up retrieval port 143, 993 IMAP, 110,995 for POP. Similarly there is no requirement for email delivery to have a web based email client like squirelmail or any other to be accessible from the outside.

Thanks for your prompt response:
1:- I could not block to access from outside the office. If my boss is outside, he want to access the webmail then what should i do at that point of time.
2:- It is just to keep track to someone who is not following the rules and take some action against them.
3: by this command grep -v 192.168.0. /var/log/httpd, we can able to track the IP who is accessing from outside the office but I also want email ID(users) who logged in.
Please make me understand by giving some example. so it is easy to undestand for me. am not expert in linux and also could not do any modification in live server.

I believe squirrelmail has its own logging option.

I think the features that plug-in adds is what you are looking for.
What options does the Boss have?
Do they always have their own laptop, smart phone, etc. such that you can preconfigure a VPN client on their device that will connect in and then they can access the squirrelmail web interface as though they were local?
Presumably if people should not be accessing from outside, you would not tell them the external host.
I doubt people are eager to check their email while home, unless it is part of their job.

What are you asking?
You are not making any changes on the email handling side. So no issues with Centos (OS) nor postfix (Mail server application handling inbound and outbound email transfer and local delivery)
The only thing you are looking to manage is the access to the web email client.

Thank you very much for always support.
You could use personal certificates as a requirement to access your web interface from outside the office.
Use a local CA to issue certificates.
THE IP is only known to you if you have control the IP. Otherwise you may have to go through courts to get the provider to identify who had the IP at the time of the access.
