Configuring integration with a mail server via POP3

If you are using the distributed solution and multitenancy mode, use the web interface of the PCN or SCN server for which you want to configure parameters.

To configure integration with a mail server over POP3:

1. Select the Sensor servers section in the window of the application web interface.

   The Server list table will be displayed.

2. Select the Sensor component for which you want to configure integration with the mail server via POP3.

   This opens the Sensor component settings page.

3. Select the POP3 integration section.
4. Set the toggle switch next to the State parameter to Enabled.
5. In the Mail server field, specify the IP address of the mail server with which you want to configure integration.
6. In the Port field, specify the port for connecting to the mail server.
7. In the Receive every field, specify the mail server connection frequency (in seconds).
8. If you want to use TLS encryption of connections with the mail server via POP3, select the Use TLS encryption check box.
9. In the User name field, specify the account name used for accessing the mail server.
10. In the Password field, specify the password for accessing the mail server.

    The mail server must support Basic Authentication.

11. In the TLS certificate drop-down list, select one of the following options:
    • Accept any.
    • Accept untrusted self-signed.
    • Accept only trusted.

    When establishing a connection with an external mail server, it is recommended to configure the acceptance of only trusted TLS certificates. If you accept untrusted TLS certificates, protection of the connection against MITM attacks cannot be guaranteed. Even though the acceptance of trusted TLS certificates also cannot guarantee protection of the connection against MITM attacks, it is the most secure of the supported methods for integration with a mail server over the POP3 protocol.

    Man in The Middle. An attack on the IT infrastructure of an organization in which a hacker hijacks the communication link between two access points, relays it, and modifies the connection between these access points if necessary.

12. If necessary, in the Cipher suite field, modify the OpenSSL settings used when establishing a connection with the mail server via POP3.

    You can view reference information on OpenSSL by clicking the Help link.

13. Click Apply.

Integration with the mail server via POP3 will be configured.

If you have deployed the Central Node and Sensor components as a cluster, you can configure fault-tolerant integration with the mail server.

To configure fault-tolerant integration with the mail server:

1. Configure Round Robin on the DNS server for the domain name corresponding to the Central Node cluster.
2. Specify this domain name in the mail server settings.

Integration with the mail server will be configured based on the domain name. The mail server will communicate with a random server in the cluster. If this server fails, the mail server will communicate with another healthy server in the cluster.
