Kaspersky Secure Mail Gateway is integrated into the existing corporate mail infrastructure and is not a standalone mail system. For example, Kaspersky Secure Mail Gateway does not deliver email messages to recipients and does not manage user accounts.
You can integrate Kaspersky Secure Mail Gateway into the corporate mail infrastructure in one of the following ways:
Before configuring integration of Kaspersky Secure Mail Gateway via an edge gateway, specify whether or not SMTP verification of recipient email addresses is enabled on the edge gateway to which Kaspersky Secure Mail Gateway will be relaying messages from internal domains.
You can configure the basic settings of Kaspersky Secure Mail Gateway integration into the corporate mail infrastructure using the Quick MTA Setup Wizard as well as integrate Kaspersky Secure Mail Gateway into the corporate mail infrastructure through the web interface of the application.
After you complete all steps of the Quick MTA Setup, Kaspersky Secure Mail Gateway resets all values of MTA setting and replaces them with values that you specified in the Quick MTA Setup Wizard.
