Noongar Posted March 14, 2012 Share Posted March 14, 2012 How can I increase simultanious mail delivery in Postfix? According to the manual I need to use 'transport_destination_concurrency_limit' in the master configuration file, well I did this and now my mail server has stopped working. transport_destination_concurrency_limit = 1000 Quote Link to comment Share on other sites More sharing options...
gizmola Posted March 14, 2012 Share Posted March 14, 2012 I think you misunderstood the manual. "transport" in this case, is meant to be a placeholder for an actual transport method. It is not a parameter in and of itself. If you did want to effect outbound smtp connections then you'd want to set smtp_destination_concurrency_limit. Even if that were not the case, 1000 is far too high of a value, since it is a "per domain" setting. Just to give you an idea, the default for one of these settings is "20", based on the mapping driven via the In the main.cf look for #local_destination_concurrency_limit = 2 #default_destination_concurrency_limit = 20 Uncomment default_destination_concurrency_limit and increase it to something like 40-50 and see how that goes.
