14.5.3 SPAM/Virus/Malware 360
If a backup MX is used it also has to perform an SPF check.
Otherwise it will be used to bypass SX-GATE's SPF filter
and render it useless. You might want to drop the backup
MX.
Own external systems
If you have configured a restrictive SPF entry for your own domain, you might
have to enter some of your own external systems here. This is the case if the
system sends e.g. status reports or critical warnings by mail and uses your own
protected domain as sender.
14.5.3-D Virusscan
Virusscan enabled
Activate this switch to scan all incoming and outgoing emails which pass the SX-GATE
mail server for viruses. As an exception, email generated on the system level of SX-
GATE like e.g. status reports and backups will not be checked. However emails written
in the webmail interface of SX-GATE will be scanned.
A functional virusscanner must be installed on SX-GATE if
you want to use this feature. The virus scanner licenses
are not included with SX-GATE and must be purchased
separately. Further information about supported or already
installed scanners can be found in the menu "Modules >
Virusscanner". The installation of a virusscanner also has to be
made there.
If a virus is found, the infected email will temporarily be stored in the "virusmails"
quarantine directory. Only the user "admin" is able to access this directory via the
console, secure shell, telnet, FTP or IMAP4. Furthermore, if the detected virus is a
makro virus or the EICAR virusscanner testpattern, the sender of the mail will be
notified.
Mail notification when virus found
If requested, an administrator will be informed by email of every discovered virus. The
notification will give details of the infected email.
14.5.3-E MIME filter
All options on this screen refer to email in MIME format. MIME is commonly used to
compose HTML emails and emails with attachments.
