Installing GFI MailSecurity

Before you install GFI MailSecurity, check the points below:

1. Make sure that you are logged on as Administrator or you are using an account with administrative privileges.

2. Save any pending work and close all open applications on the machine.

3. Check that the machine you are installing GFI MailSecurity on meets the system and hardware requirements specified earlier in this chapter.

To install GFI MailSecurity follow these steps:

1. Run the GFI MailSecurity setup program by double-clicking on the MailSecurity10.exe file. The installation wizard will perform some unpacking operations and then display the Welcome page. Click Next to continue.

2. Read the license agreement displayed in the License agreement page and click I accept the terms in the license agreement if you accept the terms of the license agreement. Click Next to continue the installation.

3. Type the administrator email address in the Administrator Email box. If you bought a license for GFI MailSecurity, type it in the License Key box. If you do not have a license yet and want to evaluate GFI MailSecurity, leave the default evaluation license key in the License Key box. Click Next to continue the installation.

NOTE: When you use the evaluation license key, you will be able to use GFI MailSecurity for 10 days. If later you decide to buy GFI MailSecurity, you will not need to install GFI MailSecurity again – entering the purchased license key will be sufficient.

4. Setup will now ask you to select the mode that GFI MailSecurity will use to retrieve the list of your email users. You must select one of the following options:

•

Yes, all email users are available on Active Directory. – Select this option to continue installing GFI MailSecurity in Active Directory mode. In this mode, GFI MailSecurity creates user-based rules, for example Attachment Checking rules, based on the list of users available in the Active Directory. This means that the machine on which GFI MailSecurity is being installed must be behind your firewall (for example, Mail Server) and must have access to the Active Directory containing all your email users (i.e., the machine on which GFI MailSecurity is being installed must be part of the Active Directory domain).

•

No, I do not have Active Directory or my network does not have access to Active Directory (DMZ). – Select this option to continue installing GFI MailSecurity in SMTP mode. In this mode, GFI MailSecurity will create user-based rules, for example Attachment Checking rules, based on the list of email users/addresses imported from your mail server. You must select this mode if you are installing GFI MailSecurity on a machine that does not have access to the Active Directory containing the complete list of all your email users. This includes machines on a DMZ or machines that are not part of the Active Directory Domain. However, you can still choose this mode to install GFI MailSecurity on machines that do have access to the Active Directory containing all your email users.

Click Next to proceed with the installation.

5. You now need to select the server where you want to host the GFI MailSecurity configuration pages. On this server, two virtual directories are created to host the configuration pages and the quarantine RSS feeds. You can specify custom virtual directory names if you want, or else leave the defaults.

NOTE: If you are installing on a Microsoft Exchange Server 2007 machine, the IIS SMTP service is not required, since it has its own built in SMTP server. In such a case, the SMTP Server Setup area is not displayed and you can click Next to continue and go to step 7 directly.

GFI MailSecurity relies on the IIS SMTP service to send and receive SMTP mail. It binds to your default SMTP virtual server (i.e., the server specified in the MX record of your DNS Server). However, if you have multiple SMTP virtual servers on your domain, you can bind GFI MailSecurity to any available SMTP virtual server. To change the default SMTP connection, select the required server from the list of available SMTP Virtual Servers provided in this dialog box.

NOTE: After installing the product, you can still bind GFI MailSecurity to another SMTP virtual server from the GFI MailSecurity Configuration (GFI MailSecurity > Settings > Bindings). For more information, refer to the ‘SMTP server bindings’ section in the ‘General Settings’ chapter.

Click Next to continue the installation.

6. Setup will now search your network and will import a list of your Local Domains from the IIS SMTP service. GFI MailSecurity determines if an email is inbound or outbound by comparing the domain in a sender’s address to the list of local domains. If the address exists in the list, then the email is outbound. Check that all your Local Domains have been included in the list on display. If not, make sure to add any unlisted domain after the installation completes. For more information, refer to the ‘Adding local domains’ section in the ‘General Settings’ chapter. Click Next to continue.

7. Setup will now ask you to define the folder where you want to install GFI MailSecurity. GFI MailSecurity requires approximately 50 MB of free hard disk space. Additionally, you must also reserve approximately 200 MB for temporary files. Click Change to specify a new installation path or click Next to install in the default location and proceed with the installation.

NOTE: If you are installing GFI MailSecurity on a x64 machine, it will be installed under the c:\program files (x86)\ folder.

8. The installation wizard has now collected all the required installation settings and is ready to install GFI MailSecurity. If you want to make changes to these settings, click Back. Otherwise, click Install to start the installation process.

9. During the installation, you are prompted that the setup needs to restart the SMTP services. Click Yes to restart these services and finalize the installation.

NOTE: If you are installing on a Microsoft Exchange Server 2007 machine, you will not be prompted to restart the SMTP service.

10. When the installation completes, click Finish to close the installation wizard.

NOTE: If you are installing on a Microsoft Exchange Server 2007 machine, the installation will launch the GFI MailSecurity Post-Installation Wizard. Refer to the following section for information on how to use this wizard.
