How To Install and Configure InterScan Messaging Security Virtual Appliance

In this guide we will install and configure Trend Micro InterScan Messaging Security (Virtual Appliance) 8.5 step by step, The environment this installation is being built on is VMware Vshpere 5.5 and the Interscan messaging appliance will be protecting Exchange 2010, however the configuration will apply to Exchange 2007 and also Exchange 2013. We start by Installing the Virtual Appliance into VSphere.

How To Install Interscan Virtual Appliance Into VMware

To install the Virtual Appliance we need to create a Virtual Machine. I recommend you give the Virtual Machine a minimum of;

  1. 8 Gig of RAM
  2. 4 CPUS
  3. 250 GIG HD
  4. When creating the VM select Linux and Centos 4/5 64bit

Once created upload the ISO or browse to the ISO you have downloaded on the client machine, set the VM to boot from the ISO as seen below.

After click next at the welcome screen you will a screen with the settings we setup during the appliance install, if you are happy with these click skip.

You can configure multiple IMSVA`s, the next screen allows you to do so, in our environment we are using a single parent device so we select next.

One the next screen we need to enter all the domains we want to accept mail from. The easiest way to get this information is to log into the Exchange EMC and go to the accepted domains tab and copy the domains configured there.

Next we configure our notification settings, this is where configure system messages from the IMSVA, also we specify the email address that the mail comes from. We can also specify headers and Footers, here you would user for example “Spam Mail Detected”.

Next up is LDAP, this is where we tie our domain to the IMSVA, this is useful if we want to create reports based on users accounts and its also useful for managment. As seen in the screen shot below, you need to enter the FQDN of your domain controller and also the domain administrator username and password. Do so then click next.

The next option relates to Trend Micro Control Manager. If you use this product to control other Trend products such as IWSS or Server protect you can configure this section the allow TMCM to manage IMSVA, I do not run TMCM so I skip this step.


We are now almost fully configured to allow the product to work. we must now activate the IMSVA by entering our product keys. Do so then you will see the final summary screen. Accept it and continue.

That is the basic installation and configuration of the IMSVA covered. By default all the anti spam and anti virus settings are at default.
