SMTP-Gateway 5.5 for Linux/Unix 7
• Update the anti-virus databases. The application retrieves updates from
the update servers of Kaspersky Lab.
The application detects and cures infected objects using the anti-virus
databases. During scans, the contents of each file are compared to the
sample code of known viruses contained in the database.
Please keep in mind that new viruses appear every day and
therefore we recommend maintaining the anti-virus databases
in an up-to-date state. New updates are made available on
Kaspersky Lab update servers every hour.
• Configure and manage Kaspersky SMTP-Gateway either from a remote
location using Webmin web-based interface, or locally, using standard OS
tools such as command line options, signals, by creating special
command files or by modifying the configuration file of the application.
• Monitor the anti-virus protection and view the statistics and application
logs.
1.1. What’s new in version 5.5
Version 5.5 of Kaspersky SMTP-Gateway has been enhanced with the following
additional features as compared with version 5.0:
• Access and routing rules are defined based not only on domain masks,
but on recipients address masks also.
• External files can be included into main configuration file.
• By administrator’s request the application can append to email messages
(as an extension header field) information about their scan status, anti-
virus software version, and the date of the anti-virus databases used for
scanning.
• By administrator’s request, the application can append to email messages
a disclaimer text generated according to a template defined by the
administrator. Different disclaimer messages may be specified for various
groups of recipients.
• Application working queue management (queue reviewing, message
removal from queue, scanning and sending a specified message ahead of
the general queue).
• Management of messages moved to quarantine, backup storage and to
archives of received and sent messages (attribute reviewing, message
removal, sending the isolated messages to their original recipients).
• An opportunity to restrict the application working queue size.
