SMTP-Gateway 5.5 for Linux/Unix
After you enter the command, the application will be installed automatically.
3.3. Installation procedure
Installation errors can occur for a number of reasons. If an error
message is displayed, make sure that your computer satisfies the
hardware and software requirements (see section 1.3 on p. 8 and that
you have logged into the system as a root.
To install the application on the server, follow the steps below:
Step 1. Preparing the system
At this stage, the system creates the system group and user account for the
application. The default group is kavusers and the default user account is
kavuser. In future, the application will start under this user account (not root) to
provide additional security for your system.
Step 2. Copying application files to destination directories
on your server
The installer starts copying the application files to the destination directories on
your server. For a detailed description of the directories where the application
files will be copied, see section A.1 on p. 78.
If you installed the application from an rpm package, then you should
run the postinstall.pl script (present by default in the
/opt/kav/5.5/smtpgw/setup/ directory) to perform the following steps.
Step 3. Post-installation tasks
The post-installation configuration includes the following steps:
• Configuring the smtpgw component (see section 3.4 on p. 23).
• Installing and registering the license key.
If you have no license key at the time of installation (for example, if you
purchased the application via the Internet and have not received the
license key yet), you can activate the application after installation before
its first use. For details see section 4.4 on p. 47. Please note that if the
license key is not installed, the anti-virus databases cannot be updated
and the smtpgw component cannot be started during the installation
process. You will have to do it manually, after the key is installed.
