The 'Emergic MailServer' is a complete solution for mid-sized businesses. It's actually a Linux based system that requires at least a Pentium class 1 GHz processor, 256 MB RAM, 40 GB hard disk, CD-ROM for installation, 10/100 Mbps network card and finally an internet connection. Apart from the basic mail server it also provides you with a Chat server, DNS server, Firewall, Spam filtering, Anti-virus support and it also has built-in proxy and caching server.

It has a browser based management system, which makes it easy-to-use. You can access it from any other remote system through a web browser, over a secure channel. With the help of the browser management tool, the mail server can also be restarted remotely. It also has an external mail fetcher, which helps its users to download mail from any external mail server and deliver it to their mail box.

For testing the Mail Server, we had setup a small prototype of an actual scenario. We used a Pentium 4 3.2 GHz machine, with 1 GB of RAM, 40 GB hard disk and a 10/100 network card installed in it. For internet connectivity we used a leased line connection. The installation of Emergic MailServer was simple and easy like any of the Linux distribution. Now, once we had installed the OS on the machine, for configuring it we opened its web interface on one of its client systems. It used a HTTPS link for admin login, which is secure and hence, is good for such kind of mail servers. Creating users was very easy. We were able to create ten different users with a single click. Moreover, you also have an option for adding more than ten users at once, by simply uploading user-id files in CVS format. It also has an option of 'Detailed Add.' In this, apart from giving simply user-id you can specify the employee-id, contact details, and allocate the amount of space that a user should use on the mail server. For antivirus testing, we sent a number of viruses as an attachment in mails. And it very effectively stopped and deleted those mails, sending across an e-mail to us notifying the e-mail ID from which the e-mail was sent and to which e-mail-ID. Checking the spam control, it worked fine. It successfully blocked the spam e-mail ID. As it has the proxy server, we used one of its clients for the test. We got access to the internet and then we restricted the client from viewing some of the commonly browsed site. So, you can restrict the site to be browsed by the specified client.

Apart from all these, there are some add-on features also. like an Advance proxy , in which you have time based, IP, MAC and group wise restrictions. It also provides HTTP scanning, ADS synchronization and SMS alerts, which is e-mail notification on your cell phones, but these are paid add-ons.

You can get the graphs for CPU utilization and other parameters to kep a tab on the health of your mail server

Bottom Line: If you are looking for an all in one package for your enterprise, then this is a good one
