We are aware of email deliverability issues with the Barracuda network. Our upstream email provider has confirmed this is a widespread issue affecting many providers and are working to resolve the issue as soon as possible. We currently do not have an ETA on a resolution to this issue, but will post updates as soon as we have additional information to share. Thanks for your patience while we work to understand the cause of the problem.
