The Email tab allows you to configure event notification by email.
In the Recipients (email addresses) field, specify the email addresses to which the application will send notifications. You can specify multiple addresses in this field, by separating them with semicolons.
In the SMTP servers field, specify mail server addresses, separating them with semicolons. You can use the following values:
- IPv4 or IPv6 address
- DNS name of the SMTP server
In the SMTP server port field, specify the number of an SMTP server communication port. The default port number is 25.
If you enable the Use DNS MX lookup option, you can use several MX records of the IP addresses for the same DNS name of the SMTP server. The same DNS name may have several MX records with different values of priority of receiving email messages. Administration Server attempts to send email notifications to the SMTP server in ascending order of MX records priority.
If you enable the Use DNS MX lookup option and do not enable usage of TLS settings, we recommend that you use the DNSSEC settings on your server device as an additional measure of protection for sending email notifications.
In the Subject field, specify the email subject. You can leave this field empty.
In the Subject template drop-down list, select the template for your subject. A variable determined by the selected template is placed automatically in the Subject field. You can construct an email subject selecting several subject templates.
In the Sender email address: If this setting is not specified, the recipient address will be used instead. Warning: We do not recommend using a fictitious email address field, specify the sender email address. If you leave this field empty, by default, the recipient address is used. It is not recommended to use fictitious email addresses.
If you enable the Use ESMTP authentication option, you can specify the ESMTP authentication settings in the User name and Password fields. By default, the option is disabled, and the ESMTP authentication settings are not available.
You can specify certificates for an authentication on an SMTP server. To do this, click the Specify certificate link and do one of the following:
- Browse for an SMTP server certificate file:
You can receive a file with the list of certificates from a trusted certification authority and upload the file to Administration Server. Kaspersky Security Center 13 Linux checks whether the certificate of an SMTP server is also signed by a trusted certification authority. Kaspersky Security Center 13 Linux cannot connect to an SMTP server if the certificate of the SMTP server is not received from a trusted certification authority.
- Browse for a client certificate file:
You can use a certificate that you received from any source, for example, from any trusted certification authority. You must specify the certificate and its private key by using one of the following certificate types:
You must specify a file with the certificate and a file with the private key. Both files do not depend on each other and the order of loading of the files is not significant. When both files are loaded, you must specify the password for decoding the private key. The password can have an empty value if the private key is not encoded.
You must upload a single file that contains the certificate and its private key. When the file is loaded, you must then specify the password for decoding the private key. The password can have an empty value if the private key is not encoded.
The Notification message field contains standard text with information about the event that the application sends when an event occurs. This text includes substitute parameters, such as event name, device name, and domain name. You can edit the message text by adding other substitute parameters with more relevant details about the event.
If the notification text contains a percent sign (%), you have to type it twice in a row to allow message sending. For example, "CPU load is 100%%".
Clicking the Send test message button allows you to check whether you configured notifications properly: the application sends a test notification to the email addresses that you specified.
Clicking the Configure numeric limit of notifications link allows you to specify the maximum number of notifications that the application can send during the specified time interval.
