I have also recently been looking at different servers for email. As we have servers and a lot of internet bandwidth i feel it is stupid to use a “hosted solution” for internet email and website service. I decided to use linux boxes for all our servers, i am fairly new to Linux but after working with it for over a year now I do not regret the decision… Especially for our business model. I tested the following packages:
After installing configuring and trying to setup each package i found that the Zimbra “open source” package was by far the simplest and easiest to setup and use. Really it took only about an hour after installation to be sending and receiving, remotely as i have a remote office from the servers, email calendering and mobile messaging. Including all services running on SSL certificate based connections.I highly recommend this product - Zimbra.

I have been evaluating on some management tools for the VoIP Telco service provider. This is what i have found:
There is a company called ManageEngine http://manageengine.adventnet.com/ they have some great products that are easy to setup and use. I am using the syslog and netflow Analyzers. With these products and properly setup Cisco routers and switches, i can get an instant picture of my network with really all the tools to check that things are running properly. The Netflow Analyzer shows bandwidth usage, protocol usage, QoS Mapping, and top talkers. With this product you can get a clear picture of who is connecting to your network and what they are doing.
The Syslog tool is great, i am using it to gather events from the Linux Servers and our routers around the world. I am basically looking at ACL violations and for port status change. It also works well and it is easy to instal in a RedHat EL 5.0 and 4.0 Server.
I was able to install and have both systems collecting information in a few hours.
I am also using MRTG to monitor our Cat6500 and our 7600’s, this was a little tricky to get going in Linux compared to the windows version but once i had the basic understanding of how to do it - it was very simple. MRTG is also a very powerful information gathering tool to help understand what is actually happening inside your network.
I am running the 3 services on one server with Redhat 5.0 server virtualization is a new feature, It looks like a wonderful tool i just am not quite ready to start that now…
