On February 24, 2021, GlobalSign will have to withdraw some intermediary GlobalSign certificates for compliance reasons. This affects, among others, all “PersonalSign certificates” issued before November 12, 2020 and expiring after February 24, 2021. The affected customers have already been informed about this process by GlobalSign via email. NoSpamProxy customers who obtain their S/MIME certificates from a GlobalSign EPKI must exchange the affected certificates by February 17.
Certain software versions will no longer be supported in the future version 14 of the NoSpamProxy. To avoid problems when updating from version 13.2 to version 14, you should check your infrastructure early and update software that is no longer supported. The following discontinuations do not affect version 13.2 but only version 14.
Currently, due to a security vulnerability, criminals are apparently able to smuggle malicious code into iPhones and iPads via emails. Affected are iOS devices on whichenen the software is installed in version 13.4.1 or a previous version up to version 6 .

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.
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.

Emails are a common part of our private and professional communication. However, there seems to be no awareness of the vulnerability of each individual email sent. In many cases, emails travel across a variety of servers and countries, regardless of whether the recipient lives on a different continent or just on a different floor in the same building. The structure of the internet makes this possible.
As a result, anyone with the neccessary technical knowledge can intercept, read or even change emails at any node during transport. And he or she can write emails in your name.
How to use SPF-authenticated servers in “Corporate email servers” 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 […]
