Nowadays, most of us can hardly imagine living without using e-mail. Certainly, electronic mail has replaced traditional mail in many cases, becoming an efficient tool for communication and marketing. We use e-mail every day, starting from personal messages and finishing on purely business-related matters: job applications, subscriptions, reservations, transactions, promotional vouchers, invoices, on-line shopping, etc. A great number of important and confidential information flows from one inbox to another one and we can never be sure of its safety.
Now, let’s imagine a large company, where this number increases along with the series of promotional materials, newsletters, business offers, job enquires, clients complaints, support requests, inter-departments conversations and plain rubbish messages with no value for the company. How can we possibly manage such a mass of information and keep all the messages in order and properly secured?
A smart email filter seems to be a perfect solution for this problem.
Email filtering is a function build in some email management programs. Its role is to monitor and control contents of messages coming into and out of the organization as well as between its employees. The content filtering strategy is up to an administrator who can customize it according to his company specific needs. CodeTwo Exchange Rules Pro is an example of a very advanced email management system. It contains a dictionary of typical email phrases, so the administrator assigns selected words or sentences to a specific category, e.g., Support, Spam or Confidential Information. Then, based on the ascribed actions for the certain categories, the program adequately reroutes, encodes or blocks the messages.
