  Content Analysis Mailshell 3.0 SpamContent)	Examines the content of messages in detail, including address fields, subject, headers, SMTP envelope content, email format, design and layout, image layout, hyperlinks, contact information, language and origin.
  Reputation Checking (using Mailshell Spam Detection Network & Bayesian analysis)	Sender reputations are determined using comprehensive 'real-time' databases of IP addresses, domains and email addresses of known spammers. Bayesian analysis is used to combat attempts to hide sender identity.
  Bulk Mail Detection (Mailshell SpamBulk)	Identifies if a message or similar messages were sent in bulk by creating 'fingerprints' based on message elements that are the hardest for spammers to fake or change.
  Phishing Protection (Mailshell SpamTricks)	Identifies special formatting used to evade spam filters and for phishing attacks and economical bulk mailings (including image-only messages, HTML obfuscation and manipulation using relays). Analysis of the message header includes time stamps and the SMTP envelope.
  SMTP Validity Checking	Checks for malformed email (usually either spam or designed to attack mail server/client vulnerabilities).
  Grey Listing	Mail from unknown senders may be temporarily rejected. Genuine email servers (as opposed to zombies or botnets) usually resend after a short delay - if a 2nd attempt is made, the sender is automatically added to the list of known senders.
  Remote Blackhole List (RBL)	Email Security has the option to utilize RBL services (maintained databases of IP addresses that are acting as open mail relays for bulk spamming).
  Sender Domain Spoofi ng	Rejects any incoming email that falsely uses an internal domain in the 'from' address.
  User-confi gurable Spam Treatment Controls	Users have the option to add email addresses to their own blacklists or whitelists and set automatic rules for changing subjects, replacing content or sending to a quarantine mailbox. Partial domains can also be matched and included.
  Per User Quarantine	Allows each email address to have a separate quarantine as opposed to a single mailbox. Users receive a daily report of "spam-trapped" email which they can then use to view and release email.
