Email clients

Integration of ESET Internet Security with your email client increases the level of active protection against malicious code in email messages. If your email client is supported, integration can be enabled in ESET Internet Security. When integrated into your email client, the ESET Internet Security toolbar is inserted directly into the email client (the toolbar for newer versions of Windows Live Mail is not inserted), for more efficient email protection. Integration settings are located under Advanced setup (F5) > Web and email > Email client protection > Email clients.

Email client integration

Email clients that are currently supported include Microsoft Outlook, Outlook Express, Windows Mail and Windows Live Mail. Email protection works as a plug-in for these programs. The main advantage of the plug-in is that it is independent of the protocol used. When the email client receives an encrypted message, it is decrypted and sent to the virus scanner. For a complete list of supported email clients and their versions, refer to the following ESET Knowledgebase article.

Even if integration is not enabled, email communication is still protected by the email client protection module (POP3, IMAP).

Turn on Disable checking upon inbox content change if you experience system slowdown when working with MS Outlook. This can occur when retrieving email from the Kerio Outlook Connector Store.
