Hi there, I've been looking for some days for a solution I need to create for a customer. What we want to achieve is throttling the delivery of mails in the queue. Right now we are using 'default_destination_rate_delay = 1s' which allows us to send approx. 3600 to each destination maximum in 1 hour timeframe. But we want to be more specific like 5000 mails globally,or 16000 globally, whatever we want to do. I've looked into PolicyD to achieve this, but I am stuck at the implementation of it at the queue system of Postfix; Right now I can only see it work with the smtpd_recipient_restrictions and smtpd_end_of_data_restrictions configuration option but not with the queue service. Am I missing something or I am overthinking it?
Kind regards, Martijn
