IT infrastructures today are regularly exposed to dangerous and sophisticated attacks by hackers. With the growing number of attacks, the technological maturity of the attack methods used increases: Emotet, WannaCry, Locky, DDOS attacks or Zip bombs repeatedly threaten companies and authorities, and in many cases cause considerable damage.

New verdict confirms: Messages in emails have legal effect even if they are filtered out and moved to the spam folder.
So-called false positives always pose a risk for many anti-spam solutions. These emails that are incorrectly recognized as spam are then either deleted or moved to quarantine or to the spam folder.
Ransomware such as Locky, WannaCry and GandCrab has been making headlines lately. Criminals use this type of malware to gain access to individual files or the entire computer. At the same time, they prevent access by the rightful owner by means of encryption. The owner is allowed access only after a ransom has been paid.
The University of Rostock replaces Sophos and Vamsoft with the central email relay NoSpamProxy to ensure secure and uninterrupted email communication for more than 16,500 users. With NoSpamProxy Protection, students and staff avoid spam and malware as completely as technically possible.
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.

The #Efail debate has caused great uncertainty among users and IT departments regarding the effectiveness of email encryption. Headlines such as S/MIME and PGP hacked were not only factually incorrect, but also led some self-proclaimed experts to advise against the use email encryption in general. The fact that the problem is not S/MIME or PGP itself was completely ignored. In reality, encryption is bypassed by getting the email client to send the plain text of the email to the attacker.
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 […]
