Email Protection functionality depends on your plan. If your account settings differ from the ones described below, read the Knowledge Base article Advanced Email Security For Exchange for more information.
To manage or view Email Protection settings, navigate to CONTROL PANEL > Services > Email Protection:
Email Protection uses multi-layer spam and anti-virus filtering engines that, besides checking against real-time blacklists, relies on a sophisticated analysis of message headers and text to determine the potential legitimacy of an email.
When a message meets a spam threshold, the filter can route such message to the Junk Email folder, User Quarantine, Admin Quarantine, it can deliver the message to the Inbox folder with the tags [SPAM] or permanently delete message depending on the options enabled. If the sender is on the whitelist (Safe Senders) either for the account or for the individual mailbox, spam checks will not be performed for the message to secure the delivery of them. Spam threshold can also be modified in the Email Protection settings.
Email protection provides additional options for anti-phishing and anti-spoofing filtering using multiple settings for routing the phishing messages to Quarantine, Junk, Inbox folder with the tag [POSSIBLE PHISHING] or by permanently deleting it.
Note: if you are unable to locate some messages, it is possible that they have failed the basic connection checks. Please contact Support or submit a Message Tracking request to find out why the messages were not delivered.
Three levels of Email Protection are available:
The following checks are called basic and are always performed:
- Check against RBLs (Real-time Black Lists) provided by
CloudMark, Spamhausand Invaluement.com
- Check for empty FROM field in Headers
- Check for a valid fully-qualified sender's (FROM) email address
- Check for a valid domain in the FROM address (check for a valid A or MX record)
- Check for valid recipient addresses within your organization
If an email message does not pass one of these checks, it is not accepted by the mail servers for delivery to recipients.
