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.

Whitelist is the list of trusted email addresses. The content from the whitelisted email IDs is allowed to skip the spam protection filtering policy and is not tagged as SPAM.

This is helpful if you find that some genuine email IDs are detected as SPAM or if you have blacklisted a domain but want to receive emails from certain email addresses from that domain.

Setting spam protection rule for Blacklist

Blacklist is the list of email addresses from which all emails are filtered irrespective of their content. All the emails from the addresses listed here are tagged as "[SPAM] -".

This feature is useful particularly if your server uses an open mail relay, which is used to send and receive emails from unknown senders. This mailer system can be misused by spammers. With blacklist, you can filter incoming emails that you do not want or are from unknown senders both by email IDs and domains.

To add email addresses in the blacklist, follow these steps:
