Due to an unexpected issue, our email flow has been changed back to flow through our on-premises exchange servers instead of the Barracuda ESS. This was done to address an issue where email relayed from some trusted servers/domains was being rejected by Barracuda.
Impact: Email that had been relayed through our email servers from trusted servers was being rejected and held in queue. These messages were eventually processed when the original email flow was reestablished. No email was lost due to this issue.
