We use postfix on a CentOS server to accept incoming mail, then do some filtering, then send the message on to our real mail server where we will pickup the mail. The postfix server sometimes has long delays when it tries to send to our real mail server. We will see delivery logs like this:

          Messages are queued due to delivery errors. Such errors can be: DNS error, a full mailbox or nonexistent mail recipient.




          why does that cause delays in the message over 1000 seconds




          Queue times are configured in main.cf file.
          According to postfix documentation




          The minimal time between attempts to deliver a deferred message; prior to Postfix 2.4 the default value was 1000s.




          If 1000sec is too long for you, you can change the timer. I advise you to read the entire postfix tuning-guide before making any changes.



          Finally you can Flush the queue(force postfix to immediately process the queue) by using



          sudo postqueue -f


          or



          sudo postfix flush

            • When the message keeps saying "(queue active)", and it's because of one of the errors you named, "DNS error, a full mailbox or nonexistent mail recipient," Is the only way to find out the specific error by manually troubleshooting? What about increasing the verbosity of the logs?

              You don't need to increase the verbosity. Default settings are good to troubleshoot those errors. What's in the log file?

            We haven't been able to discover at this point what the "(queue active)"




            Postfix maintains queues for the pending mails, "queue active" indicates there are mails in the queue.



            To see queued mails issue:



            sudo mailq


            or



            sudo postqueue -p



            What is the cause of the "(queue active)" message.




            Messages are queued due to delivery errors. Such errors can be: DNS error, a full mailbox or nonexistent mail recipient.




            why does that cause delays in the message over 1000 seconds




            Queue times are configured in main.cf file.
            According to postfix documentation




            The minimal time between attempts to deliver a deferred message; prior to Postfix 2.4 the default value was 1000s.




            If 1000sec is too long for you, you can change the timer. I advise you to read the entire postfix tuning-guide before making any changes.



            Finally you can Flush the queue(force postfix to immediately process the queue) by using



            sudo postqueue -f


            or



            sudo postfix flush
