Error message
If the rate limit is exceeded, the following error occurs:

Emails that are rejected using the code 5.7.1 must be resubmitted as soon as the rate limit is exceeded again.
Measurement details
The rate limit is measured on the basis of relative time. The respective intervals relative to the transmission attempt are therefore taken into account for each transmission attempt. Please note that the daily rate limits are not automatically reset at 0:00, but are evaluated relative to the last 24 hours.
