Hi Hank!
Apologies for the delayed response.
I'd like to provide you with an update on the current status.
On one hand, we have deployed features to mitigate issues related to making updates with multiple references (#1486).
This prevents the creation of an RPSL with a lot of references. We are continuing to investigate ways to further improve this process.
On the other hand, the second round of notification you received was due to some notifications bouncing back and being incorrectly
handled as mail updates instead of bounced messages. We have addressed this issue by correctly handling these messages as Multipart/mixed Bounced
and Auto-submitted Messages (#1490).
We are actively monitoring the situation to ensure the issue is resolved and to determine if additional features are necessary.
We will publish a post-mortem once we are confident the issues raised have been mitigated.
Thank you for your patience and understanding.
Regards
Miguel Herrán
