Has this issue been fixed? I just received the same message and cannot see where to unblock the account. We're on Build 7719. This is the message:
From: "System Administrator"
Sent: 3/9/21 1:07 PM
Subject: Auto spam notification
This is an automatic spam notification message generated by [my-email-server]
The sender [my-customer] has exceeded the abuse detection rule of 100 outbound messages in 1 minutes.
Any outbound messages from this account over the next 1440 minutes will be rejected.
I looked at all the built-in anti-spam settings everywhere I could find any, and non of them are set to 100 per minute.
What system produces this email?
There's another thread from 2018 that doesn't look like it was resolved.
