Application structure and typical deployment scenarios 17
• Specify in the routing table transfer of all scanned messages to the mail
system via port 1025. In order to do this, specify the following value in the
[smtpgw.forward] section of the application configuration file:
ForwardRoute=*@company.com [host:1025]
where: *@company.com is the mask for recipient addresses
host – name of the your corporate mail server.
• Change the settings of the existing mail system for receiving messages
from the application via port 1025. This will ensure receipt of all incoming
mail messages and delivery of these messages to the local users within
the protected domains of the company.
• Set up the existing mail system to transfer all messages it receives to the
application via port 25. This will ensure anti-virus scanning of all outgoing
mail messages from the local users.
• Specify the list of all corporate local domains as a value for the
ProtectedDomains option in the [smtpgw.network] section of the
application configuration file ("*" and "?" wildcards can be used). Mail
messages for the specified domains will be scanned.
The operation algorithm of the application, when the latter is installed on a
dedicated server, is identical to its operation on the same server with an email
system, but the settings for this scenario will differ. IP address of the server,
where the application is installed must be included in MX records corresponding
to the protected domain.
In order to install the application on a dedicated server:
• Configure the application for mail receipt via port 25 on all network
interfaces of the server. In order to do this, specify the following value in
the [smtpgw.network] section of the application configuration file:
ListenOn=0.0.0.0:25
• Specify in the routing table transfer of all scanned messages to the mail
system via port 25. In order to do this, specify the following value in the
[smtpgw.forward] section of the application configuration file:
ForwardRoute=*@company.com [host:25]
where: *@company.com is the mask for recipient addresses
host – name of the your corporate mail server.
Application configuration for this deployment scenario will be
implemented by default during the installation process.
