Version 7.8 now available

On 16th April 2012 the version 7.8 of the Net at Work Mail Gateway has been released to the public. This release enables you to link your mail environment to the De-Mail system. This enables you to send and receive De-Mails in your accustomed mail client like Microsoft Outlook or Lotus Notes. The flexibility to securely exchange mails is improved by the all new PGP encryption feature. Another premiere is the introduction of the Outlook add-in which gives you control of the way mails are being processed by the Net at Work Mail Gateway.

Previous versions of the Net at Work Mail Gateway can be upgraded in-place. The installation- and upgrade notices can be found here.

The following new features, changes and bugfixes are included in version 7.8:

Changes and new features:

De-Mail-Connector

The connection to the De-Mail-System conforms to latest BSI policy. As mentioned before the solution easily integrates in your existing mail environment.

PGP implementation

Now it is possible to create, manage and use PGP Keys for secure mail communication. “RSA” and “DSA with Elgamal” algorithms are available to create your own pair of PGP keys.

PDF Mail

PDF Mail enables you to encrypt and secure a mail message without the use of cryptographic keys. This is achieved by converting the mail into a password protected PDF document. The password can either be set by the sender or automatically be generated by enQsig.

Outlook add-in

Another feature is the new Outlook add-in. Users are able to influence the behaviour of the Gateway. Outlook 2007 or 2010 are required to use the add-in now.

Management console improvements

Clipboard support has been improved. For example you can paste the list of your owned domains in the configuration dialoge or copy the details of a certificate request into the clipboard now. You can also copy the information shown on the summary pages of each role.

Improved Action “Sign and/or encrypt”

You are given the opportunity to choose “no signing” for a more granular rule set now.

Changes in standard RBL-filters

Due to stability issues the “No-more-funn” Realtime Blocklist has been removed.

Behavior on invalid encoded Base64 content

Former versions of the Net at Work Mail Gateway blocked invalid Base64 encoded mail or passed it with nearly no checks run on it. In this release it is possible to auto-correct errors in Base64 encoded content. This enables you to validate these mails more closely now.

Signature inspection report in multiple ways

Now it is possible to add signature inspection report as an X-header to the mail. This information is visualized by the new Outlook add-in. It is also possible to attach the report as a XML file to the mail. Both options must be configured in the configuration file.

Changes in DOI Send Connector

Username and password are both optional now.

Fixed issues

  • Information about replication issues were displayed after the issue has been resolved. This behaviour has been fixed. Information about database issues were displayed after the issue has been resolved. This behaviour has been fixed.
  • Replication  between the Gateway Role and the UserManagement Role has been improved.
  • Archive system will no longer archive rejected mails.
  • Missing information about synchronization of DOI connector added
  • A duplicate MIME header on signed mails is no longer added.
  • An invalid semicolon at the end of content type header is no longer added.

“No-more-Funn”-RBL should be disabled

Real Time Blocklist (RBL) “No-more-Funn” has recently become very slow to respond. This results in warning messages in Eventlog from Gateway Role with Eventid 3067. The message says:

The filter Realtime Blocklist filter took more than 60 seconds to complete. The execution of this filter has been aborted. If this happens regularly, contact the Net at Work support.

Solution:

Open “Rules” in Gateway Role. Edit all rules using “Real Time Blocklists” as filter. Open rule by doubleclick. Go to “Filters” and doubleclick “Real Time Blocklists”. Now select “No-more-funn” and click on “Remove selected entry”. Close the selection by clicking “Save and Close”. Save the rule by clicking “Save and close”.

Different rule set behaviour in the next version of Net at Work Mail Gateway

In Net at Work Mail Gateway versions smaller or equal 7.7.143, it wasn’t necessary to use wildcards to block all mails from a specific domain. For example you enter “enqsig.de” on the “Sender” tab, all mails from enqsig.de are blocked or passed through, depending on the setting you made on the “Filter” tab. However, this behaviour caused problems if you want to block a mail from andrews@enqsig.de, but mails from bob.andrews@enqsig.de should pass through.

This behaviour has now been changed. As of the next public build you’ll need to use wildcards such as “*” or “?” to block all mails from a specific domain, e.g. *@enqsig.de.

A new build will be released within the next few weeks. Please make sure that you adapt your rules according to the new behaviour before upgrading to a version of 7.7.144 or higher.

Net at Work Mail Gateway Version 7.7

Net at Work Mail Gateway 7.7 was released on July 18. This version now supports the integration of SigntrustCert, a Deutsche Post AG Trust Centre product, which makes E-mail certificate management considerably easier.
Also new is the connection to the “E-Postbrief-System”. The E-Postbrief-System makes it possible to communicate in a secure way with your business partners. enQsig now enables a direct connection to the IKG-Boxes provided by “Deutsche Post AG”.
Also Many changes already made to the software core since the 7.5 version can now be put to full use. For example, it is now possible to create several send and receive connectors that can distribute e-mails to different smart hosts based on the target domains. In addition, two new anti-spam filters have been implemented. The following list includes all of the new features:
Send certificate requests automatically
Once an administrator has applied for a Class 3 certificate with SignTrust and installed it in the Net at Work Mail Gateway, Class 2 certificates for other users can be ordered conveniently via the user management role. This considerably speeds up the process of obtaining certificates for individual users.
Connectors
Incoming and outgoing connectors can now be configured via the interface. This makes it possible to switch the Net at Work Mail Gateway from proxy mode to queue mode and forward incoming e-mails to different smart hosts using the receiving domain, for example. Of course, the same applies for outgoing e-mails.
Available send connectors:
  • Standard SMTP connector, delivering either via DNS or (possibly several) smart hosts
  • E-post connector
  • Deutschland Online Infrastruktur connector

Available receive connectors:

  • SMTP connector
  • POP3 connector (Only in combination with enQsig! In combination with NoSpamProxy, this is not a Net at Work supported environment!)

With all connectors, it is possible to assign PINs  for certificates, so TLS connection certificates saved on smart cards can be used.

E-post connector
Link the Net at Work Mail Gateway with the e-post IKG boxes (individual communication gateway, German = Individualkommunikations-Gateway). Sender domain-based routing enables multi-client capability when there are multiple IKGs. This feature is very interesting, particularly for e-mail providers.
Certificate encryption
Database certificates can now be encrypted with a master key.
Character set recognition
This is a new filter for detecting unwanted character sets. All e-mails with unwanted characters (e.g. Chinese or Cyrillic characters) receive 4 penalty points.
Certified Sender Alliance (CSA)
This is a new action for incoming e-mails. Newsletters from certified providers are classified as trustworthy. For more information on CSA, go to http://www.certified-senders.eu
UserManagement has moved
User management has now migrated completely to the user management role. Users managed here are automatically distributed to all of the connected gateway roles.
New SMS provider: AnySMS
AnySMS (http://www.any-sms.info/) is the new SMS message provider.
Upgrade
To install the new version, .NET Framework Version 4 .0 is required. After .NET Framework 4.0 is installed, version 7.7 can be installed without deinstalling 7.6. All previous settings will be retained. If you want to upgrade from a version preceding 7.6, please read the upgrade instructions first.

Support life cycle
Support for version 6.5 and previous versions will be discontinued with the adoption of version 7.7 on May 30.

Recommended Update for NoSpamProxy 7.x

Version 7.5.71 for NoSpamProxy and enQsig is available since May 28. It is a bugfix release which contains no new features. Existing installations can be upgraded in place if their version is 7.0 or above. All settings are retained in this case.

The update resolves a problem with the reporting role. Under certain circumstances, the message tracking would report a mail as “Delivery is pending” although the mail has already been delivered to all recipients.

Another bug was fixed in the Gateway Role which caused mails to be delivered unencrypted, although encryption was enforced for this mail. This could happened, when the encryption process failed unexpectedly.

Additionally, improvements regarding the handling of non RFC compliant mails were implemented.

The latest version can be downloaded from www.nospamproxy.com
