This function can only be used if a virus scanner has already
been installed on SX-GATE. The virus scanner licenses are not
included with SX-GATE and must be obtained separately.
The delivery of an email will be stopped if it contains a virus. The mail will be moved
to a quarantine directory and the local administrator will be notified by mail. Depending
on the type of the detected virus also the sender of the infected email will be notified
(e.g. for macro viruses or the EICAR virusscanner testfile). Only the administrator can
access the quarantine directory. If there was no access to a quarantined email for 10
days it will be deleted automatically.

Attachment filter
Email attachments can be filtered by SX-GATE based on the filename extension. We
recommend to enable the attachment filter as it can enhance the virus protection, even
if you are already using virusscanners. Usually a virusscanner can detect a virus only
if its signature is already known. Filtering attachments with filename extensions often
used by viruses can defang a virus which is yet unknown to the virusscanner. You could
also activate this component to enforce local policies which deny sending or receiving
emails in certain file formats.
incoming and outgoing mails
While inbound emails are quarantined, outbound emails with unwanted
attachments will be rejected.

Filter attachments with file extension
If the filename of an attachment matches one of the extensions listed here, the
attachment will be moved into a quarantine directory. The email will either be retained
as a whole or the unwanted attachments will be replaced with a warning message
before the modified email is delivered to its recipients.
