MailMarshal SMTP version 6.X supports a direct upgrade from MailMarshal SMTP 6.0 and later versions. This is a change from earlier versions. To upgrade from a version prior to 6.0, first upgrade to version 6.4.

Note: This release of MailMarshal 6.7 cannot be used to upgrade a MailMarshal 6.3 Appliance installation.

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 Marshal 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, first upgrade to version 5.5, then to 6.4, and then to 6.7

Changes in Database Structure and Prerequisites

MailMarshal can use:

Microsoft SQL Server 2008 or SQL 2008 Express
Microsoft SQL Server 2005 or SQL 2005 Express (both with Service Pack 1)
Microsoft SQL Server 2000 or MSDE 2000 (both with Service Pack 3a)

The MailMarshal CD-ROM includes SQL 2008 Express. Note: To install SQL 2008 Express on a server, you must first install .NET 3.5 SP1.

Upgrading a Single Server

To upgrade a single MailMarshal SMTP server from version 6.0 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

If you are upgrading FROM version 6.3 or above, 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 Marshal Knowledge Base article Q12776.

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 Marshal 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 Marshal8e6.
6.7 Blended Threats proxy access: To use the BTM where a proxy is require you may need to run the Engine service under a domain account. See Marshal 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.
6.5 Service Pack requirement: MailMarshal servers now require Windows Server 2003 Service Pack 2. For the full list of supported operating systems, see Hardware and Software Requirements.
6.5 .NET version requirement: The Web Components now require .NET 3.5 SP1.
6.5 database upgrade: The MessageName index on the MailMarshal database is changed during upgrade (issue MM-1957). On large databases this change could take an hour or more. Reports and Console actions may not be available while this process is occurring. The installer estimates the execution time and allows you to stop installation if required.
6.5 file type recognition updates: A number of new file types have been added to the file type recognition facility, including Open Office documents and a new PDF subtype. See the "MC" entries in Change History. You should review file type rules to ensure that new types are allowed or blocked as appropriate.
6.5 folder message release: The default action when a message is released from any folder is now "continue processing." This change affects all messages currently in folders, even if the folder was previously configured with a release action of pass through or reprocess. To set up other actions, after upgrading, edit each rule that moves or copies messages to a folder.
6.5 Image Analyzer: The new Image Analyzer has fewer advanced settings. Earlier advanced settings are not preserved on upgrade. The new Engine Sensitivity setting is set to the default 65.
The upgrade installation (6.5 and above) does not install any new rules. After upgrading, you must create rules to use any new features available in the specific release. For more information, see Marshal Knowledge Base article Q10337.
6.4 Operating System Support: As of version 6.4, MailMarshal is no longer supported on Windows 2000. You cannot install MailMarshal 6.4 on Windows 2000. If your existing MailMarshal installation is on a computer running Windows 2000, you will not be able to upgrade.
6.4: SpamProfiler: Version 6.4 introduces the SpamProfiler service. This service allows MailMarshal to pre-filter spam at the Receiver. SpamProfiler is enabled by default on new installations. As part of the upgrade process you can choose to enable SpamProfiler (strongly recommended).
- SpamProfiler requires internet access from each processing server. To configure usage and proxy options, see the Spam and Internet Access tabs of Server and Array Properties. For additional information see the User Guide and Marshal Knowledge Base article Q11927.
6.4: Disk space requirements: Version 6.4 introduces significantly higher default requirements for free disk space (1GB free space preferred). On upgrade of a single server installation, you will be warned if less than 1.5GB of free space remains. In an array installation, you should check free space on each server manually. For more details on the disk space settings, see Marshal Knowledge Base article Q11669.
6.4: POP3 aliases: Version 6.4 and above does not support POP3 aliases for domains that are outside your local domains list. If you have previously defined such aliases, after you upgrade email will no longer be delivered to them.
During the upgrade from version 6.1.8, the MailMarshal Controller may stop with an error. In most cases the Controller will restart automatically. This behavior is related to issue MM-429, first fixed in version 6.2.0.
In version 6.2 and above, the internet access proxy setting 'Preset' option is no longer available. During upgrade the 'Preset' option will be changed to 'Direct Access'.
When upgrading from a version below 6.1.6, if you have configured a range of return values for External Commands, the interpretation of the range entry has changed. Starting and ending numbers are now included (1-5 now matches 1, 2, 3, 4 and 5).
When upgrading from MailMarshal SMTP 6.0 to MailMarshal SMTP 6.X, the database upgrade will require approximately 5 minutes per GB of data. You should schedule your upgrade with this time requirement in mind.
By default the MailMarshal SMTP 6.X installation places the Unpacking or Explode folder within the MailMarshal SMTP installation folder. If your Unpacking or Explode folder is configured in another location, you can select that location on the Choose Destination Location window of the installation wizard.
Message Release codes generated by MailMarshal SMTP 5.5 will not be accepted by the Message Release external command under MailMarshal SMTP 6.X.

Uninstalling

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

To uninstall a trial installation on a single computer:

Close all instances of the MailMarshal Configurator, MailMarshal Console, and MailMarshal Reports.
