Email Security

Anti-spam protection is achieved by layering multiple filtering engines that, besides checking against real-time black lists, uses a sophisticated analysis of message header and text to determine the potential legitimacy of each message. When a message meets a certain user-defined spam threshold, the filter routes such messages to the Junk Email folder or permanently deletes it, unless the sender is on the whitelist (Safe Senders) either for the account or for the individual mailbox.

Two levels of Email Security are available:

The following checks are always performed:

  • Check against RBLs (Real-time Black Lists) provided by CloudMark, Spamhaus and 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.
