Application filter

info

Application filter of SpIDer Mail component can be configured on Dr.Web Server only. Corresponding settings are not provided on stations.

Application filter allows to configure manual interception of email traffic. In this mode, SpIDer Mail serves as a proxy server between mail clients and mail servers and intercepts only those connections that are explicitly defined in the settings. To use this mode, you also need to configure mail clients on stations.

The list of intercepted addresses includes records. Each record establishes a correspondence between settings of SpIDer Mail and a mail server.

By default, the interception list is empty. You can add the necessary records.

Configuring Mail Interception

1.Make a list of all mail servers whose connections you want to intercept and assign port numbers for these servers in arbitrary order. At this, use only unused non-system ports. The assigned numbers are called SpIDer Mail ports.

info

SpIDer Mail supports POP3, SMTP, IMAP4, and NNTP mail servers.

2.Select the Anti-virus network item in the main menu of the Control Center.

3.Click the name of the station or group in the hierarchical list of the opened window.

4.Click the Configuration > Windows > SpIDer Guard and SpIDer Mail > SpIDer Mail item in the opened control menu. Open the Application filter tab.

5.In the SpIDer Mail connections settings section, specify the following parameters:

SpIDer Mail port—SpIDer Mail port that you assigned for the mail server at step 1;

Server—the domain name or IP address of the mail server;

Port—the port number that the mail server uses.

6.If necessary, repeat the step 5 for other servers. To add one more mail server to the list, click icon-item-add.

7.To stop intercepting connections to a certain mail server, click icon-item-remove next to the item of the list that corresponds the server.

8.After you configure all necessary settings, click Save to apply the changes on the station.

9.Configure the mail client at the station to support the manual interception mode by the SpIDer Mail component.

Configuring Mail Clients

If the SpIDer Mail is configured to manually intercept connections to mail servers, change the settings of a mail client on the station as following:

1.Set the address of the incoming and outgoing mail servers as localhost.

2.Set the mail server port to the SpIDer Mail port number that you assigned to the corresponding mail server.

Usually, you need to specify the following in the mail server settings:

localhost:<SpIDer_Mail_port>

where <SpIDer_Mail_port> is the number that you assigned to the mail server.
