Service Issue: "Bounced" Activity events are not displaying in the UI, or being posted to webhooks. Messages are being sent and delivered.

We have now processed through all bounced events. There may be a few instances where the UI still only shows a "Processed" event, which means the message was successfully sent from Postmark but we were not able to accept the bounce details from the recipient's inbox provider and they have not tried to provide us with those details again since.

Thank you for your patience!

New bounced events are now being processed normally. We are still working through the backlog of older bounced events. We will continue to update with more details.

Some new bounced events are now showing up in the Activity UI, and being posted to webhooks. We are still investigating and will update shortly.

We've narrowed down the issue to Bounce events not appearing in the UI and bounce events not posting to webhooks. Messages are still being sent and delivered. We are still investigating and will update shortly.

We are investigating instances of "Delivered" events for SMTP sending being delayed, SMTP messages are being sent and delivered. API sending is not impacted.

[UPDATED] Only "Bounce" events are not appearing in the Activity UI, and they are not posting to webhooks, whether the message was sent via the API or SMTP. Messages are still being sent and delivered.
