SurfControl E-mail Filter 5.2.1 for SMTP May 2006Installing or Upgrading to E-mail Filter 5.2.1 Uninstalling or Rolling Back E-mail Filter 5.2.1 |
Welcome to
SurfControl E-mail Filter 5.2.1 for SMTP. This release contains the
enhancements and bug fixes listed below.
Improved
Spam Protection
The
implementation of the Sender Policy Framework (SPF) helps to mitigate spoofed
e-mails, phishing, fraud and spam. SPF fights
return-path address forgeries and makes it easier to identify spoofs, and
distinguishes authentic messages from forgeries before any message data is
transmitted.
Improved
Security
The
implementation of Transport Layer Security (TLS) provides secure communications
on the Internet by using an industry-standard cryptography-based protocol. TLS
authenticates the server, establishes a private, secure communication channel
that prevents eavesdropping, tampering and message forgery between mail server
communications.
Default
Compliance Rules and Dictionaries
There are now standard supplied rules and
dictionaries that you can use to filter e-mails that contain credit card
numbers, Social Security numbers and medical records.
Certificate
Generation
E-mail Filter
supports self-signed and CA (Certificate Authority)
signed certificates to enable you to use the TLS and SMTPS security features in
the Send and Receive services.
Improved
Dictionaries
Russian and
Korean dictionary packs have been added, and existing dictionaries have been
enhanced.
VIA (Virtual Image Agent) Licensing
VIA licensing now supports 1, 2 and 3 year licensing
subscriptions.
Remote Installation
E-mail Filter can now be installed remotely by using a
remote desktop or a Windows Terminal Server.
New User Interface for eSMTP commands
A new dialog has been added in the Server Configuration console in the Monitor to enable you to have more granular control in using eSMTP commands.
Multiple LDAP Support
Directory Harvest Detection now supports the ability to select multiple LDAP connections.
E-mail Connection Management
Usability improvements have been made to the ‘Pre-screening’ settings of the System Configuration controls. A new set of options - E-mail Connection Management - enable easy configuration of defenses against connection-based attacks in the SurfControl E-mail Filter. These defenses include Denial of Service, Directory Harvest, Connection Limits, RBL servers, and many more. Also note that you can now add IP addresses to the ‘Blacklist’ configuration.
