Sending large attachments by email can cause problems because images, videos or large documents often exceed the maximum file size allowed. This is becoming increasingly problematic because more and more data is generated every day. Countless image and multimedia files created using smartphone cameras are proof of this.

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
