Limit the number of messages an account can send per minute on Postfix

Hello all,

I would like to limit the number of email messages an account can send to 10 per minute.
How do I do that?

Thanks a lot

However, for general rate limiting in Postfix, you can look at the smtp_destination_rate_delay and relay_destination_rate_delay options. You can read about how those work here:
