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

News, Tech & Support, Updates

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 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.

Possibilities of Email Encryption

All Topics, News, NoSpamProxy Encryption, Tech & Support

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.
