ok thanks chrishea, jbennet and V S. I will surely do this and apply in my office. I want another question answer guys can you solve me out.

Our organization is a medium size organization with 40 employees. We have created LAN with 25 nodes. We use email as our formal communication tool. The users use Outllook as a mail client and store the sent/received emails on individual basis on their nodes. Our Company wants centralized storage and retrieval of all sent and received emails. Can you suggest a mail server which provides this facility?

Please guys solve this question also

We are a small organization. We have installed local area network at our office. Email is our main communication tool. We have a following query:

  1. Can Emails be delivered on the desk of the user without internet?
  2. Which product is the cheaper and yet efficient?
