Partial Rackspace Email Delivery Disruption - – Microsoft and SpamCop Blacklisting

This incident has been resolved.

We are pleased to share that most of the Rackspace IPs that were blocked have now been cleared. As a result, email deliverability should be largely restored. We'll continue to monitor the situation and keep you informed of any further updates if needed.

We are actively working in close coordination with the Rackspace team to resolve this issue promptly. Most of the blocked IP addresses have already been delisted, and you should see noticeable improvements in email deliverability right away. We will share further updates as soon as more information becomes available.

We are currently facing issues where some of the Rackspace Server IP addresses have been blocked by Spamcop and Microsoft. Our team is actively working with Rackspace to resolve this matter as soon as possible. We apologize for any inconvenience this may cause and appreciate your patience. Further updates will be provided as soon as more information becomes available.
As a workaround, customers may try again after some time. The system may use random IP addresses, so it is not guaranteed that the same IP will be used to send emails again.
