Trusted Email Clients Protection

Since email happens to be the most widely used medium of communication, it is used as a convenient mode to deliver malware and other threats. Virus authors always look for new methods to automatically execute their viral codes using the vulnerabilities of popular email clients. Worms also use their own SMTP engine routine to spread their infection.

Trusted Email Clients Protection is an advanced option that authenticates email-sending application on the system before it sends the emails. This option prevents new worms from spreading further. It includes a default email client list that is allowed to send emails. Email clients in the default list includes Microsoft Outlook Express, Microsoft Outlook, Eudora, and Netscape Navigator.

Trusted Email Clients Protection supports most of the commonly used email clients such as; Microsoft Outlook Express, Microsoft Outlook, Eudora, and Netscape Navigator. If your email client is different from the ones mentioned, you can add such email clients in the trusted email client list.
