Hello,I'm using 2.8.0. I've added a new transport in master.cf : slow unix - - n - - smtp -o syslog_name=slow and the following in main.cf slow_destination_rate_delay = 20 slow_destination_concurrency_limit = 3 slow_destination_recipient_limit = 2 and finally the following in my transport table : wanadoo.fr slow: The issue is that I have only 1 message sent to wanadoo.fr every 20s, I expected to see 3 with this settings, so... what I am doing wrong ?
A non-zero *_destination_rate_delay enforces a concurrency limit of 1. This also implies the minimum delay is 1 message per second, or no sub-second delays. This isn't terribly clear in the docs.
To limit this destination to ~3 messages every 20 seconds, set the delay to 6 or 7.
I have warnings like this one in logs that are certainly related to the issue : warning: mail for wanadoo.fr is using up 1301 of 1500 active queue entries
The warning is because you have so much mail queued for that destination. Hopefully you can send mail out at a greater rate than it's coming in.
also postconf does not show those slow_* added values in main.cf, is this correct ?
