What's New

For more information about additional minor features and bug fixes, see the change history.

Features New in 7.0

Automatic Updates: Updates to message unpacking are now provided (if necessary) through the Automatic Updates process that is used for SpamCensor updates. To be sure you have the latest available unpacking updates, verify that this process is correctly configured.
Changes in upgrade prerequisites: Direct upgrade is supported from MailMarshal SMTP 6.7 and above.
Changes in Operating System support: Installation on Windows Server 2008 requires SP2. Installation on SBS 2003 is no longer supported. Installation of Server components on Windows 7 and Windows Vista is no longer supported. For full details of supported installation environments, see the User Guide.
TLS enhancements: Additional functionality is available when sending and receiving via TLS.
- Use of outbound TLS is enabled by default for new installations
- TLS certificate generation supports Subject Alternative Names
- Outbound TLS supports providing a client certificate if requested
- New rule conditions are available:
  - Where message was/was not received via TLS
  - Where the negotiated TLS parameters match criteria (certificate checking)
    - Note: Checking of Certificate Revocation Lists is mentioned in documentation but NOT available in release 7.0.1.
Additional Dead Letter Rule condition: Dead Letter rules now allow the condition "where detected as spam by SpamProfiler."
Additional Dead Letter Rule actions: Dead Letter rules now allow the BCC, Send mail template notification, Set message routing, Write message classification, Move to folder, and Delete actions.
Lines before boundary handling: Messages that would previously have been deadlettered with "Too many lines before boundary" are now unpacked and scanned.
Branding: The product formerly known as MailMarshal SMTP is now M86 MailMarshal SEG (Secure Email Gateway).

Features New in 6.9

Rules structure: Email Policy is divided into Connection Policy, Content Analysis Policy, and Dead Letter Policy. Rules formerly known as "receiver rules" are now found in Connection Policy; "standard rules" are now found in Content Analysis Policy. Filtering order and behavior is not changed.
Dead Letter Rules: A new type of rule allows messages that cannot be processed to be passed through based on user matching and the text of the Dead Letter reason code.
PDF unpacking improvements: Images, attachments, and annotations are now unpacked from PDF documents. Supported images types are JPG, JPG 2000, TIF, and RAW. The PDF unpacker can be updated automatically through the MailMarshal Automatic Updates (SpamCensor updater). This improvement addresses numerous other issues with PDF unpacking. See change history for details.
Changes in upgrade prerequisites: Direct upgrade is supported from MailMarshal SMTP 6.5.1 and above.
Reports change: Marshal Reporting Console is the supported reporting interface. The MailMarshal Reports application (based on MMC and Crystal Reports) is no longer included.
Message Logs Change: Text log information for messages is now stored in each message (MML) file. Logs for delivered messages are stored in a special folder named Sent History. You can use the Configurator to change the permissions and retention period for this folder. You cannot rename it, delete it, or view it in the Console.
Database Software Support: SQL Server 2008 R2 and 2008 Express R2 are supported.

Features New in 6.8

Changes in database and upgrade prerequisites: SQL 2000 is no longer supported. Direct upgrade is supported from MailMarshal SMTP 6.4.5 and above.
Support for additional operating systems: Windows Server 2008 R2 and Windows 7 are supported for all components.
Improved database security options: Database connections can be made using Windows accounts. MailMarshal can grant limited permissions to an "operational user" for daily use (database owner permission is required for upgrades).
Dashboard (Today Page) improvements: The Console dashboard now allows you to select a time period for the statistics display. Note that the historical data is only available for times after this version is installed (earlier versions did not save the data).
Spam Management enhancements: The administrator can allow users to subscribe and unsubscribe from digests, and to add entries to Safe Senders lists when releasing a message from digests.

Features New in 6.7

SpamBotCensor: A new layer of spam filtering that efficiently identifies messages originating from spambot networks.
Blended Threats Module: A new option to identify email containing malicious URLs, using a database with zero day updates. To use the BTM you may need to run the Engine service under a domain account. See M86 Security Knowledge Base article Q12931.
Marshal IP Reputation Service: A new DNS based block list, provided by M86 Security using proprietary data.
Report Spam/Not Spam: New options in the Console allow you to report false positive and negative spam identification of messages with one click.
User Group pruning: MailMarshal can remove unused email addresses from user groups to maintain server performance.
Outbound SMTP Authentication: MailMarshal can now send SMTP credentials when making outbound connections.
Enhanced Inbound SMTP authentication: MailMarshal now supports CRAM-MD5 as well as plain text authentication.
Upgrade Tasks listing: A new page in the Configurator shows tasks that the MailMarshal administrator should complete after upgrading.

MailMarshal SEG 7.0 supports a direct upgrade from MailMarshal SMTP 6.7 and later versions. This is a change from earlier MailMarshal SMTP releases. To upgrade from a version prior to 6.7, first upgrade to version 6.7.

Please review the MailMarshal User Guide before upgrading.

For general information about upgrading issues see the remainder of this section.

Full details about upgrading from specific versions can be found in the following M86 Security Knowledge Base articles:

Q11025 Upgrading from MailMarshal 5.5 to MailMarshal SMTP 6.X
Q11026 Upgrading from MailMarshal 6.0 to MailMarshal SMTP 6.X
Q11027 Upgrading from MailMarshal 6.1.3 to MailMarshal SMTP 6.X

To upgrade from a version prior to 5.5 (not recommended), first upgrade to version 5.5, then see the above articles.

Changes in Database Structure and Prerequisites

MailMarshal no longer supports SQL 2000 or MSDE 2000.

See the Hardware and Software Requirements section for the latest list of supported SQL Server versions.
MailMarshal supports Windows Authentication as well as SQL Authentication. Mixed Mode is no longer required.

You can access a supported SQL Express version from the Prerequisites tab of the MailMarshal installation package. The "With SQL Express" version of the package also allows you to install SQL Express during the main MailMarshal installation. Note: You may need to first install .NET 3.5 SP1.

Upgrading a Single Server

To upgrade a single MailMarshal server from version 6.7 or above, install the new version over your existing version. You do not need to uninstall your existing version. The database will be upgraded in place, if necessary.

Upgrading an Array of Servers

After upgrading the Array Manager you can upgrade the processing servers through the Configurator, with no need to log on to the processing servers. For more information, see the Upgrading section in the User Guide.

Notes on Upgrading

Note: The information in this document is current as of the date of publication. To check for any later information, please see M86 Security Knowledge Base article Q14285.

7.0 Outbound TLS Configuration: You can now set outbound TLS to provide a client certificate if requested by the remote server. This setting is not enabled on upgrade, to preserve existing behavior. This setting is enabled by default for new installations. M86 Security recommends that you enable this setting if you use outbound TLS.
7.0 Inbound TLS Policy: You can now configure rules to take action based on TLS connections and TLS certificate features.
7.0 Receiver Socket Timeout: The default value for transmission timeout is now 30 seconds (the previous default was 300 seconds). Existing settings are not changed. However, M86 Security recommends the new value for most installations to enhance performance. If your internet connection is slow, you may need to set a higher value. See MailMarshal Properties > Receiver Properties > Advanced.
6.9 TLS Configuration: You can now select a minimum cipher strength to be used for TLS connections. Upgrade sets the minimum to "low" for compatibility with earlier versions. To enhance security, M86 recommends you set the value to at least "medium." Be aware that changing this setting could cause some connections to be rejected.
6.9 Deadletter Folder Retention: Upgrade resets the retention period for deadletter folders to 7 days. Any changes that you previously made using the method described in Knowledge Base article Q10260 will be lost. After upgrading, use the Configurator to set the desired values.
6.9 Policy changes: On upgrade, existing Receiver rules are moved to the Connection Policy container. Standard rules are moved to the Content Analysis Policy container. Policy groups are created as necessary. Filtering order and behavior is not changed.
6.9 File Type Identification: Version 6.9 identifies the following as executable files:
- Plain text files with extension .CMD or .BAT
- Binary unknown files with extension .COM or .EXE
- Previous versions identified these files as "text" or "binary unknown". You may wish to review and adjust your rules.
6.9 Sent History folder: Version 6.9 uses a special folder named Sent History to preserve processing logs for messages that have been successfully delivered. If you have a folder named Sent History, the installer will prompt you to rename it before you can proceed with the upgrade.
6.9 Message Logs: If you have selected the "copy message log file" feature for quarantined or archived messages, you should consider unselecting this option. The Sent History feature provides the same information automatically.
6.9 .NET version requirement: The Web Components now require .NET 4.0.
6.9 database upgrade: To resolve an issue with reporting of IP addresses, the upgrade rewrites some existing data. This process can take significant time to complete for large databases. The upgrade installer provides an estimate of the time required.
6.8 Digest setup: To allow users to subscribe or unsubscribe from digests, use the Configurator to edit the properties of each digest and make the selection. To allow user selection of digests from the SQM website, see the Administrator tab of SQM. To provide an unsubscribe link in digest emails, use the variable {UnsubscribeUrl}. For more information see the User Guide and Help.
6.8 Sophos for Marshal upgrade: If you are using Sophos for Marshal, upgrade Sophos for Marshal to version 1.0.3 before upgrading MailMarshal. This step is required due to the change in the MailMarshal registry key location.
6.8 database change: If you are using SQL 2000 or MSDE with an earlier version of MailMarshal, you must move the database to SQL 2005 before upgrading MailMarshal. For assistance see Knowledge Base article Q11646.
6.7 Reputation Service: The Marshal IP Reputation Service is licensed with a customer number and activation code that you must enter when enabling this service. For more information, please see M86 Security Knowledge Base article Q12878.
6.7 Reputation Service Upgrade: If you enabled the Marshal IP Reputation Service in an earlier version of MailMarshal, the file MarshalRBL.xml will be overwritten during the upgrade. The upgrade process saves the customer number and activation code to the Registry, and makes a copy of the file in the Config folder on the Array Manager server as MarshalRBL.xml.bak.
- If you added any custom attributes such as SkipFirstIPs, after upgrading you must copy this information from the file MarshalRBL.xml.bak to MarshalRBL.xml on the Array Manager server, and then commit configuration to update the processing node servers.
6.7 Blended Threats licensing: The Blended Threats Module is licensed using a flag in the product key. To try this module, obtain a special time-limited key from M86 Security.
6.7 Blended Threats proxy access: To use the BTM where a proxy is required you may need to run the Engine service under a domain account. See M86 Security Knowledge Base article Q12931.
6.7 User Group Pruning: After upgrading, for best results do not enable User Group Pruning immediately. At the time of upgrade, no existing items in user groups will be marked as "seen." Enable pruning after a month, or whatever time you determine as the pruning cycle for each group. For more information about pruning, see the User Guide and Help.

Uninstalling

MailMarshal can be installed in a variety of scenarios. For full information on uninstalling MailMarshal from a production environment, see the MailMarshal SEG User Guide.
