Step 5. Finishing integration of Kaspersky Secure Mail Gateway through an edge gateway (SMTP verification of recipient email addresses is enabled)

At this step, check the settings you have specified for integrating Kaspersky Secure Mail Gateway into the corporate mail infrastructure and confirm your choice.

When integration into the corporate mail infrastructure is completed, the following settings of Kaspersky Secure Mail Gateway are configured automatically:

SPF authentication of message senders is disabled.
Do not enable SPF authentication of message recipients because the message sender is the edge gateway from which Kaspersky Secure Mail Gateway receives messages.
DMARC authentication of domains from which Kaspersky Secure Mail Gateway receives messages is disabled.
Do not enable DMARC authentication of domains because Kaspersky Secure Mail Gateway receives messages from an intermediate gateway.
SMTP verification of recipient email addresses is enabled.
Do not disable SMTP verification of recipient email addresses because SMTP verification of recipient email addresses is enabled on the edge gateway.

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.
