No, I believe the service which is behind these emails is called FMN. It is very fragile for multiple reasons where it falls over for different reasons all the time. It is the reason why it is on the top of being replaced by CPE in this quarter (aka by October-ish). Until that happens, please be aware that these notifications are likely to come in bursts as things go up and down. I would also suggest that turning off as many notifications as you can would help the load as one of the largest email problems Fedora Infrastructure has is the many people who have turned on getting email on a lot of events.
