Email Filtering
Chapter 15: SMART Management and Subscription Services 337
Email Filtering
There are two Email Filtering services:
Email Antivirus
When the Email Antivirus service is enabled, your email is automatically scanned for the detection and
elimination of all known viruses and vandals. If a virus is detected, it is removed and replaced with a
warning message.
Note:
The Email Antivirus subscription service differs from VStream Antivirus in the
following ways:
Email Antivirus is centralized, redirecting traffic through the Service
Center for scanning, while VStream Antivirus scans for viruses in the
Nokia IP60 gateway itself.
Email Antivirus is specific to email, scanning incoming POP3 and
outgoing SMTP connections only, while VStream Antivirus supports
additional protocols, including incoming SMTP and outgoing POP3
connections.
You can use either antivirus solution or both in conjunction. For information on
VStream Antivirus, see
Using VStream Antivirus on page 309.
Email Antispam
When the Email Antispam service is enabled, your email is automatically scanned for the detection of
spam. If spam is detected, the email’s Subject line is modified to indicate that it is suspected spam.
You can create rules to divert such messages to a special folder.
Note:
Email Filtering services are only available if you are connected to a Service
Center and subscribed to the services.
