IMF Tune - Bringing Back the Exchange Connection Filter
Email Pre-processing, Fixes in IMF Tune Update
A new IMF Tune update is available for download, bringing more functionality and some important fixes.
The email pre-processing functionality announced earlier, is the most significant addition delivered in this update. This is being surfaced through four Advanced Rule conditions, ticking off some highly requested improvements.
Recipient Email Conditions
Most organization assign email addresses using schemes of the type:
IMF Tune matches the first segment of the email address (
Whereas the complete email address in this email signature doesn't:
When using these conditions keep in mind that:
Digits in Sender Addresses
Users relying on free email services sometimes also use digits, especially when having trouble finding a unique address. On the other hand, business entities rarely use digits, since these make them look less professional.
This filtering condition is fine-tuned by specifying the digit count threshold. Organizations that deal exclusively with business clients won't see many legitimate senders with digits in their emails. Thus they can afford a low threshold, maybe blocking addresses with 3 or more digits. Other organizations with a broader pool of senders (such as Universities) may want to be more lenient and allow for more digits.
NULL sender addresses are used in Delivery Status Notification (DSN) emails. The most well-known DSN type is the Non Delivery Report (NDR) sent when an email fails delivery.
In addition, by combining multiple conditions we can target specific DSN sub-categories. This would require us to better understand DSNs. Check the article Understanding NDRs and other DSN Reports for more details.
Fixed - "Power Shell not found!" Installation Error
Occasionally we are encountering problems with servers having missing/incorrect registry information under the Power Shell registry hive. These servers would still have a well-functioning power shell. We encountered this problem on Windows 2019 but the same issue might arise on earlier Windows server versions.
IMF Tune depends on Power Shell for installing some of its components. In this fix we are replacing Power Shell detection, such that to allow IMF Tune to proceed with the installation. Any serious Power Shell problems are now caught by the installation further down the line.
Fix - Uninstall Not Removing IIS ASP.NET Application
When the IMF Tune Moderator/Reporting component is installed on a Windows 2019 server, a subsequent uninstallation would not remove the ASP.NET application components from within IIS 10. This update includes the necessary fix for these components to be correctly removed.
If running an earlier version of the Moderator on Windows 2019, you may encounter this problem on upgrading. In that case just go ahead with uninstalling and re-installing the latest Moderator. The re-installation will perform the necessary cleanup and re-create the components. Subsequent uninstallations will correctly remove the ASP.NET application.
This information applies to IMF Tune v8.0 build number 8.0.105.06. If IMF Tune is already installed you can verify the current build number from the configuration interface under the Miscellaneous category.
