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.

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