At around 16:15 UTC on 16 April 2024 a configuration update was deployed to our forwarding mail servers. The update inadvertently included some old configuration that we used when we initially rolled out SRS mail forwarding a few months ago. As a result of this error some mail sent to customer forwarding addresses may have been bounced back to the sender.
The configuration has been corrected today 17 April 2024 as of 19:05 UTC and the old configuration has been purged from our management systems to prevent this from occurring again.
