This plugin for Haraka implements outbound rate limits using redis as the shared store.
npm install --save https://github.com/haraka/haraka-plugin-outbound-rate-limit.git
Then add outbound-rate-limit to your config/plugins, and create the configuration file for your domains.
Configuration is set in your config/outbound_rate_limit.ini file.
The defaults are:
delay=30
redis_host=127.0.0.1:6379
[limits]
;example.com=10
The counts for the limits are the maximum concurrency for a given outbound domain.
The delay value are the number of seconds to delay before trying to send this mail again. The concurrency will be checked on every attempt to deliver the mail.
