Hi there,

I did add a new slow transport to my Postfix configuration but this doesn't looks to work Messages passes correctly in the slow transport but they aren't rate limited.

Currently, I'v been setting this up in my master.cf:

slow unix - - n - 1 smtp -o default_destination_concurrency_limit=1 -o initial_destination_concurrency=1 -o smtp_destination_concurrency_limit=1 -o in_flow_delay=2s -o syslog_name=slow

Any idea why my messages aren't rate limited?

Regards,
