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. To exploit the vulnerability, the victim must open a document specially prepared by the attacker. Even if there is no direct danger for NoSpamProxy customers, we recommend installing the update. Further information and the download links can be found here.

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.

Similar to Microsoft Exchange, some NoSpamProxy features can only be enabled through a PowerShell cmdlet. Specifying an “SPF-authenticated corporate email server” is one such feature. Entries of this kind facilitate the maintenance of NoSpamProxy enormously. “Corporate email servers” define the servers of a company that are allowed to use owned domains in email sender addresses. By default, IP addresses, subnets, host names, TLS-authenticated hosts, and Office 365 tenants can be specified.
