S/MIME Zertifikate

Secure e-mail communication with S/MIME certificates

, ,

Every email is vulnerable – theoretically. The journey of an email through the Internet is long, although the speed of transmission often makes this forget. Emails can be intercepted, read, or even modified during transportation. At least if they are sent unencrypted. The consequences may be devastating: Qinthe ancendatous damage, loss of data or loss of image are at risk for all those who exchange emails unencrypted. In addition, unencrypted emails are already no longer compatible with data protection – also with regard to the General Data Protection Regulation (GDPR)

One way to enable secure email communication and send information confidentially and securely is to use PKI-based e-mail encryption and signature. PKI stands for Public Key Infrastructure, and the most common standard for such encryption is S/MIME (Secure/Multipurpose Internet Mail) Extensions).

Outgoing e-mails are rejected with “Unable to relay”

, ,

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

Wie sicher ist E-Mail-Verschlüsselung?

How Secure is Email Encryption?

,

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.

Welche Möglichkeiten der E-Mail-Verschlüsselung gibt es?

Possibilities of Email Encryption

, , ,

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.
