4.1.2.1.1 Compatibility
Certain email programs may experience problems with POP3 filtering
(e.g., if receiving messages with a slow Internet connection, timeouts
may occur due to checking). If this is the case, try modifying the way
control is performed. Decreasing the control level may improve the
speed of the cleaning process. To adjust the control level of POP3
filtering, from the Advanced Setup tree, navigate to Antivirus and
antispyware > Email protection > POP3, POP3s > Compatibility.
If Maximum eciency is enabled, infiltrations are removed from
infected messages and information about the infiltration is inserted
before the original email subject (the options Delete or Clean must be
activated, or Strict or Default cleaning level must be enabled).
Medium compatibility modifies the way messages are received.
Messages are gradually sent to the email client – after the last part
of the message is transferred, it will be scanned for infiltrations.
However, the risk of infection increases with this level of control. The
level of cleaning and the handling of tag messages (notification alerts
which are appended to the subject line and body of emails) is identical
to the maximum eciency setting.
With the Maximum compatibility level, you are warned by an
alert window which reports the receipt of an infected message.
No information about infected files is added to the subject line or
to the email body of delivered messages and infiltrations are not
automatically removed – you must delete infiltrations from the email
client.
4.1.2.2 Integration with email clients
Integration of ESET Smart Security with email clients increases the
level of active protection against malicious code in email messages.
If your email client is supported, this integration can be enabled
in ESET Smart Security. If integration is activated, the ESET Smart
Security Antispam toolbar is inserted directly into the email client,
allowing for more ecient email protection. The integration settings
are available through Setup > Enter entire advanced setup tree…
> Miscellaneous >Email client integration. Email client integration
allows you to activate integration with supported email clients.
Email clients that are currently supported include Microsoft Outlook,
Outlook Express, Windows Mail, Windows Live Mail and Mozilla
Thunderbird.
Select the Disable checking upon inbox content change option if
you are experiencing a system slowdown when working with your
email client. Such a situation may take place when downloading email
from Kerio Outlook Connector Store
Email protection is activated by clicking Setup > Enter entire
advanced setup tree… > Antivirus and antispyware > Email client
protection and selecting the Enable email client protection option.
4.1.2.2.1 Appending tag messages to email body
Each email scanned by ESET Smart Security can be marked by
appending a tag message to the subject or email body. This feature
increases the level of credibility for the recipient and if an infiltration is
detected, it provides valuable information about the threat level of a
given email or sender.
The options for this functionality are available through Advanced
setup > Antivirus and antispyware > Email client protection. You
can select to Append tag messages to received and read mail, as
well as Append tag messages to sent mail. You also have the ability
to decide whether tag messages are appended to all scanned email, to
infected email only, or not at all.
ESET Smart Security also allows you to append messages to the
original subject of infected messages. To enable appending to the
subject, select both the Append note to the subject of received
and read infected email and Append note to the subject of sent
infected email options.
The content of notifications can be modified in the Template
added to the subject of infected email field. The above‑mentioned
modifications can help automate the process of filtering infected
email, as it allows you to filter email with a specific subject (if
supported in your email client) to a separate folder.
4.1.2.3 Removing infiltrations
If an infected email message is received, an alert window will display.
The alert window shows the sender name, email and the name of the
infiltration. In the lower part of the window the options Clean, Delete
or Leave are available for the detected object. In almost all cases,
we recommend that you select either Clean or Delete. In certain
situations, if you wish to receive the infected file, select Leave. If Strict
cleaning is enabled, an information window with no options available
for infected objects will displayed.
