We see high transient errors for one of our shared IP pools.
The response we get returned from your infrastructure when trying to deliver emails is the following:
smtp;452 Hello throttled sender. You have exceeded the maximum number of recipients this hour (50)
Is there anything we can do or you can do to allow us to deliver our client's emails to your infrastructure within an timely manner and without a high amount of transient errors.
Please do also let me know if you need more information.
