4.2.4. Additional tasks
A discussion of additional tasks helps understand enhanced functionality of the
application. The examples below help the administrator tune up the application
for performing particular tasks to extend the functionality of the application and to
tailor the application for the conditions and requirements of a particular
organization.
4.2.4.1. Block delivery of messages to recipients
Sometimes, the administrator needs to block delivery of certain messages to the
recipients.
For example, a message containing important information, that needs to be
saved, may be flagged as suspicious. This important information may be
corrupted or lost during disinfection. In this case, it is recommended that you
block this message and send it to Kaspersky Lab for analysis.

and cure all infected objects in mail messages.
• Block messages containing suspicious, corrupted, and
password-protected objects and infected objects, which the

suspicious, and corrupted objects in email messages and about
