Did i got i right?
expiry, queue, scantime we need to delete from config file/not need them at all?
Delete expiry and scantime and set --queue 1 just to be sure. This settings are provided by Kalroth!
Yes and it works. I had found some settings to lower my reject ratio... But finaly the best thing i've done , it's simply remove scantime and expiry, queue was already set at 1.
