All sending should now be back to normal. Sorry for the errors and delays this morning!
We've resolved the issue SMTP API bounces, so you shouldn't be receiving those errors any more. Sending/receiving delays should also return to normal soon.
We're also seeing some delays in outbound sending at the moment. The team is working on fixing these issues as soon as possible.
You may currently see some SMTP API bounces for valid sender signatures. We are investigating the issue.
