4.3.1 Email client protection
Email protection provides control of email communication received through the POP3 and IMAP protocols. Using
the plug-in for Microsoft Outlook and other e-mail clients, ESET Smart Security provides control of all
communications from the email client (POP3, MAPI, IMAP, HTTP). When examining incoming messages, the
program uses all the advanced scanning methods included in the ThreatSense scanning engine. This means that
detection of malicious programs takes place even before being matched against the virus signature database.
Scanning of POP3 and IMAP protocol communications is independent of the email client used.
The options for this functionality are available through Advanced setup > Web and email > Email client protection.
ThreatSense engine parameter setup – The advanced virus scanner setup enables you to configure scan targets,
detection methods, etc. Click Setup... to display the detailed virus scanner setup window.
After an email has been checked, a notification with the scan result can be appended to the message. You can elect
to Append tag messages to received and read mail or Append tag messages to sent mail. Be aware that on rare
occasions tag messages may be omitted in problematic HTML messages or forged by some viruses. The tag
messages can be added to received and read email, sent email or both. The available options are:
Never – No tag messages will be added at all.
To infected email only – Only messages containing malicious software will be marked as checked (default).
To all scanned email – The program will append messages to all scanned email.
Append note to the subject of received and read/sent infected email – Select this check box if you want email
protection to include a virus warning in the subject of an infected email. This feature allows for simple, subject-
based filtering of infected emails (if supported by your email program). It also increases the level of credibility for
the recipient and if an infiltration is detected, provides valuable information about the threat level of a given email
or sender.
Template added to the subject of infected email – Edit this template if you wish to modify the subject prefix format
of an infected email. This function will replace the message subject "Hello" with a given prefix value "[virus]" to the
following format: "[virus] Hello". The variable %VIRUSNAME% represents the detected threat.
4.3.1.1 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, integration can be enabled in ESET Smart Security. When
integration is activated, the ESET Smart Security toolbar is inserted directly into the email client, allowing for more
efficient email protection. Integration settings are available through Setup > Enter advanced setup... > Web and
email > Email client protection > Email client integration.
Email clients that are currently supported include Microsoft Outlook, Outlook Express, Windows Mail, Windows Live
Mail and Mozilla Thunderbird. For a complete list of supported email clients and their versions, refer to the
following ESET Knowledgebase article.
Select the check box next to Disable checking upon inbox content change if you are experiencing a system
slowdown when working with your email client. This can occur when retrieving email from the Kerio Outlook
Connector Store.
Even if integration is not enabled, email communication is still protected by the email client protection module
(POP3, IMAP).
