The action Project Heimdall is available since version 13.0 as a preview in NoSpamProxy. It currently ensures that metadata for email attachments and URLs are collected and uploaded to the NoSpamProxy cloud. This includes the file name, file sizes, the SHA-256 hash value, the MIME type (as recognized by NoSpamProxy) and the transaction ID.
In March, Microsoft will suppress insecure connection requests to Windows domain controllers. This change was announced in August. NoSpamProxy customers can sit back and relax because they only have to check the Active Directory synchronization of NoSpamProxy – in case this hasn’t already been done. If necessary, firewall ports will have to be adjusted.
Recently, our support has received reports that the Cyren Integration Service is detected as malware by Windows Defender on systems with the NoSpamProxy Gateway role and the NoSpamProxy WebPortal.

Since Microsoft has already discontinued support for Outlook 2007 in October 2017, we now announce the discontinuation of support for Outlook 2007 for the NoSpamProxy Outlook add-in as of June 30, 2019. If you are still using the Outlok add-in with Outlook 2007, we recommend that you upgrade to a current version of Office or Outlook (at least Outlook 2010) due to the security risks associated with Office 2007.
With the last Microsoft patchday on September 12th, a security update for the .NET framework was released, which closes a critical vulnerability.

A new wave of spam emails and viruses is currently affecting IT systems around the world. Since early November 2018, fake invoices, bank account warnings and other forged documents containing malicious code in the form of banking trojan Emotet are being distributed.
Dear NoSpamProxy customers,
since a few hours we see in customer environments that send outgoing e-mails from O365 via NoSpamProxy the error “Unable to relay”. We found that Microsoft uses a new certificate to identify all Office 365 email servers, which was issued by a GlobalSign CA rather than Microsoft’s own CA. The NoSpamProxy security check to see if the server is a valid “company e-mail server” fails and the e-mails are rejected. A new Fast Channel Version is available to fix this issue.
We apologize for any inconvenience caused.
Your NoSpamProxy Team
