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.

Outgoing e-mails are rejected with “Unable to relay”
News, Tech & Support, UpdatesDear 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.
