of overall security by disabling scanning of various file types, but we do
not recommend doing so for users who want the best protection.
For maximum user protection, Kaspersky SMTP-Gateway recognizes
more than 700 formats of archived and compressed files. This is
essential for anti-virus security, because harmful executable code may
be hidden inside files of any recognized format. However, despite the
daily growth in the number of viruses detected by Kaspersky SMTP-
Gateway (approximately 30 new viruses appear daily) as well as the
ever increasing number of recognized file formats, each subsequent
version of our product functions faster than the previous one. That is
achieved through the use of new, exclusive technologies, such as
iChecker™, developed at Kaspersky Lab.
Question: Why do I need the key file? Will my Kaspersky SMTP-
Gateway work without it?
No, Kaspersky SMTP-Gateway does not work without a license key.
If you are still deciding whether or not to purchase Kaspersky SMTP-
Gateway, we can provide you with a temporary key file (trial key), which
will only work either for two weeks or for a month. When this period
expires, the key will be blocked.
Question: What happens when the license expires?
After expiration of the license, Kaspersky SMTP-Gateway will continue
operating, but updating of the anti-virus databases will be disabled.
Kaspersky SMTP-Gateway will continue cleaning infected objects but
only using the old anti-virus databases.
If such a situation arises, notify your system administrator and contact
the company where you have purchased Kaspersky SMTP-Gateway or
Kaspersky Lab directly for license renewal.
Question: Kaspersky SMTP-Gateway does not work. What should I do?
First, check if a solution for your problem is provided in this
documentation, especially in this section or on our website.
In addition, we recommend that you apply for support to the distributor
from whom you purchased Kaspersky SMTP-Gateway or write to our
Technical support service ([e-mail]
) or to the address
contained in the license key information.
