How to rate-limit in nginx, but including/excluding certain IP addresses?

Postfix throttling for outgoing messages

I need Postfix to send outgoing messages (from local PHP) with a certain rate. Say, one message in 120 seconds. Any messages exceeding this rate should be queued (delayed) and delivered later.

Policyd is not what I’m looking for. I don’t need limiting overall number of messages sent. I need a pause (120s) between any two messages beeing sent.
