About the key

A key is a sequence of bits with which you can activate and subsequently use the program in accordance with the terms of the End User License Agreement. A key is generated by Kaspersky Lab.

You can add a key to the program in one of the following ways: apply a key file or enter an activation code.

After you add a key to the program, the key is displayed in the program interface as a unique alphanumeric sequence.

Kaspersky Lab can blacklist a key over violations of the End User License Agreement. If the key has been black-listed, you have to add a different key to continue using the program.

There are two types of keys: active and additional.

An active key is the key that is currently used by the program. A trial or commercial license key can be added as the active key. The program cannot have more than one active key.

An additional key is a key that entitles the user to use the program, but is not currently in use. An additional key automatically becomes active when the license associated with the current active key expires. An additional key can be added only if the active key is available.

A key for a trial license can be added only as the active key. A key for a trial license cannot be added as an additional key.

An additional key can be added only if the active key is available.

The following types of keys are used for Kaspersky Secure Mail Gateway:

Fully-functional key. When this key is added, the program works in full-functionality mode, performing scans for spam, phishing, viruses and other types of malware, as well as Content Filtering, Mail Sender Authentication, and scans of messages using Kaspersky Anti Targeted Attack Platform.
Key for Anti-Virus protection. When this key is added, the program performs scans for viruses and other types of malware, Content Filtering, Mail Sender Authentication, and scans of messages using Kaspersky Anti Targeted Attack Platform. The program does not perform a spam scan. The status label assigned by the program to a message following a scan contains information about limited functionality.
Key for Anti-Spam and Anti-Phishing protection. When this key is added, the program performs scans for spam and phishing, Content Filtering, Mail Sender Authentication, and scans of messages using Kaspersky Anti Targeted Attack Platform. The program does not scan for viruses or other malware. The status label assigned by the program to a message following a scan contains information about limited functionality.

The type of additional key should match the type of the previously added active key. If the type of the additional key does not match the type of a previously added active key, the available program functionality changes in accordance with the type of the additional key when the additional key becomes active.

Anti-Spam and Anti-Virus databases are updated regardless of key type.
