We are aware our unauthenticated SMTP relay cluster has been subject to relay abuse by a compromised client. Currently SMTP services are suspended on the cluster.
UPDATE 01 – 22:30
SMTP services on the cluster remain suspended while we review. Further updates will be provided on the 29/07/2020
UPDATE 02 – 09:15 – 29/07/2020
After a full review. Due to the age of the platform, End of life support on the OS, extremely low usage levels (less than 0.1%) and the lack of support for enhanced security such as DKIM and DMARC. We have decided to withdraw the platform form service.
For customers who where using the service, We would advise migrating to authenticated SMTP provided via your web hosting provider or signing up with a free relay such as https://www.smtp2go.com/
We understand change is unwelcome, but after review we feel this is in the interest of all who still use the platform to protect your domain and others.
