We are happy to announce the public beta release of next ORF update. ORF 6.7 brings a range of new features and usability improvements to the ORF Log Viewer and the management of quarantined attachments.

Read on to learn what’s changed, check the known issues section and get the new beta.

What's New?

NEW: Microsoft® Windows Server 2022 Support

ORF now officially supports Windows Server 2022.

NEW: Attachment Quarantine Manager

Allows resending, exporting and deleting quarantined attachments that were saved to the file system. Accessible via the ORF Administration Tool (Attachment Filtering) or the ORF Log Viewer (Tools).

NEW: Attachment resending settings

A new tab called Resend has been added to the Attachment Filtering settings dialog.

NEW: Log Viewer - Resend attachment

Quarantined attachments can be resent to the original recipients with a single click using the Tools menu or the right-click context menu.

NEW: Log Viewer - Event grouping

Events logged for a given email are now grouped together for easier overview (limited support on IIS SMTP servers).

NEW: Log Viewer - New columns

Four new columns have been added to the Log Viewer:

  • Author: The (RFC5322.From) email address that email clients actually display to recipients.
  • Source IP: The IP address of the mail server that sent the email.
  • Remote Peer IP: The IP address of the mail server that connected to the ORF server.
  • Related Test: The ORF test related to the event record.

NEW: Log Viewer - New sorting options

Three new sorting options have been added to the Log Viewer column headers:

  • Username
  • Organizational domain
  • Top-Level domain

IMPROVED: Log Viewer - Right-click menu

The right-click context menu has been restructured for easier view and navigation.

IMPROVED: Log Viewer - Remote Control

The Remote Control feature which allows sending IP and email addresses from the ORF Log Viewer to various ORF lists has been improved:

  • The content of the Author and HELO fields have been added to the list of items available for sending to ORF lists.
  • You can now send multiple items at once to ORF lists, and specify the comment.

IMPROVED: Log Viewer - Right-click filter

You can now filter for multiple selected items at once from the right-click context menu.

BUGFIX: Reporting Tool - DMARC reporting

The Hits and Contribution statistics were incorrectly calculated in the DMARC filtering reports.

Further minor changes and improvements



Be sure to read the Installation Notes before installing the beta version.

ORF Fusion

for Microsoft® Exchange and IIS SMTP Service
version 6.7 BETA 01
released on May 18, 2022
expires on August 16, 2022
size 13.1 MB
Download System requirements

A separate download of the ORF management tools is available below. Install this package on workstations to manage ORF remotely. Note that management tools are included in the full installer packages above (for local management).

ORF 6.7 Beta R01 Management Tools-only Installer

The 6.7 Management Tools are not backward compatible. You can only manage ORF 6.7 installations with the 6.7 Management Tools package. Side-by-side installation of 5.x or 6.x Management Tools is currently not available.

Installation Notes

Please consider that this is pre-release software and may contain bugs. Install the beta for testing purposes only.


When upgrading from an existing ORF installation, make sure to create a configuration backup prior the upgrade, as described by the Configuration Backup Guide. If you need to revert back to the previous version, this backup can be used to restore your previous version quickly.

Important Exit from the Windows Event Viewer MMC before the upgrade (see this FAQ article).

Known Issues

The list below contains the issues that we know about the current beta release. This list is maintained during the lifetime of the beta; be sure to check back here before reporting an issue. Issue severity levels are explained in the FAQ.

Severity Issue

Access Violation Error

ORF may occasionally log an access violation error - we are still investigating the cause of the error. This error does not affect the mail flow or the stability of the ORF service.

Slow log loading and log manipulation speed

ORF logs take longer to load and manipulate (e.g. filtering) when events are displayed in groups, which is especially noticeable when working with larger log files (>48 MB; >100K events). We will improve the responsivity and performance of the Log Viewer during the Beta. If you need to view larger log files, you can switch back to the "ungrouped" view before opening the log files (Log Viewer: View > Group events (F9)).

Attachment Quarantine multi-server support (Log Viewer)

When connected to multiple servers, the ORF Log Viewer throws an error when you try to resend or view a quarantined attachment. Until this issue is resolved, we recommend that you configure the ORF servers to use the same network share if you want to centrally manage quarantined attachments (ORF Administration Tool: Blacklists > Attachment Filtering > Settings > Quarantine).

Some website links may not work

A few links pointing to our website from ORF and its help system will not be available until the final release of ORF.

Reporting bugs

When reporting bugs, please share any information with us that you consider important for reproducing the bug. A few tips on what we might need:

When sensitive information (such as logs) needs to be shared, please send these to [email protected].

You can report issues of all severity, even the smallest things like typos or grammatical errors.


What are the limitations of the beta version?

The beta release is fully functional and contains all planned features. It is also time-limited and the current release will expire on August 16, 2022. We will release either the final version or another beta release before the above date.

What do the different issue severity levels mean?

We define four simple levels for issue severity.

Cosmetic issues are harmless and do not affect any functionality. These are typically typos, grammar mistakes and other interface issues.

Minor issues render some functionality of ORF broken, but they are generally harmless and do not affect the overall operation of the product.

Medium severity issues cause an important ORF functionality to be broken. If you rely on the affected functionality, you may not be able to use the beta until a fix is released.

Major issues affect the overall reliability of the software. If such issue is published, you are recommended to stop using the beta until a fix is released. Make sure to read the description to understand the risks.

Unknown severity is assigned to issues where the scope of the issue has not been determined yet.

Setup says "DeleteFile failed; code 5.", how do I fix this?

You may receive "DeleteFile failed; code 5. Access denied." error from the Setup regarding orfeesvc.exe when updating an existing ORF installation.

This is caused by a program that locks the Windows Event Log message resource embedded in the ORF Service binary orfeesvc.exe. The typical offenders are the Windows Event Viewer MMC and software that uses WMI (Windows Management Instrumentation) for reading the Windows event log.

To fix this problem, exit from the Event Viewer MMC and click "Retry". If the file is still locked, shut down any software temporarily which monitors the Windows event log and try again.

If the above does not help, go to the ORF installation directory and rename orfeesvc.exe to orfeesvc.bak, then click "Retry".

Can you add Feature X?

We are happy to hear your suggestions and they may make it into a future ORF version.

What are the system requirements of ORF Beta?

The system requirements have not changed since the last ORF release. Check the current system requirements here.

The Management Tools package can be installed on any modern Windows desktop OS (Windows XP or later).

Just how stable is the beta?

Early ORF releases were tested in-house by Vamsoft developers for weeks on various platforms. Due to this, we expect that most issues that may arise will be lightweight.

Be sure to visit the beta forums every once in a while, we will publish any bug reports there. You can also subscribe to the RSS feed of the beta forum.

Can I upgrade to the new beta from ORF X.X?

Yes, the beta setup is fully backward compatible and will update any earlier ORF Fusion or Enterprise Edition release.

Will I be able to upgrade to the final version from the beta?

Yes, you will be able to upgrade from the beta in-place.

How do I revert to ORF X.X?

You can revert by uninstalling ORF Beta and installing a previous ORF version. Once the installation is complete, restore the configuration backup you made previously (see the Configuration Backup Guide).

When is the final version expected?

It depends on the beta test progress. We are committed to release a stable ORF version to our clients, so the final release can be expected only once the preview release reaches a reasonable level of reliability.

Will I get ORF free of charge upon its final release?

Your subscription guarantees access to any new ORF releases within the validity period — this includes ORF 6.7. Be sure not to let your subscription expire and you will get the new ORF at no additional cost.
