Hi, I had a question regarding the main.cf parameter “default_destination_concurrency_limit”. The man page (man 5 postconf), states it is: “The default maximal number of parallel deliveries to the same destination.” and that this applies to the smtp(8) delivery agent.
This got me wondering . . . how would one adjust this parameter ? I am thinking it is only through benchmarking trial and error, as a number of factors would seem to affect this (server load, bandwidth, etc.). But then I was thinking if it was through trial and error, how was the value of “20” determined when most people running Postfix will have varying equipment for their server ? [1] Thanks, - J [1] I ask this as there a couple of other parameters in the main.cf config file that seem to fall into this category and I am wondering if there is a more efficient method of determining the values for my server or whether the solution is also through trial and error.
