What does the Postfix maillog entry say?

I suspect the messages are in qfiles/in/ and not being processed by any
Assuming the method from
the entries in the QRUNNERS list are tuples of (name, count,
name is the qrunner name; you're good there.
count is the total number of slices for that queue. This should be a
power of 2 multiple of number_of_machines,
this_machine_number is the number of this machine; a number from 0 to
number_of_machines - 1
number_of_machines is the number of machines on which mailmanctl and
qrunners are running
I'm not clear on what number_of_machines is in your case, but it
certainly isn't more than 3. If mailmanctl and qrunners are only
running on this one machine, its entries should be (name, 1,0,1). If
the mail gateways are also running qrunners, then this machine should
have entries (name, 3,0,3) and the others (name, 3,1,3) and (name,
With (name, 5,0,5) and the others (name, 5,3,5) and (name, 5,4,5), the
queues are partitioned into 5 slices and only slices 0, 3 and 4 are
being processed leaving 40% of the messages waiting in the in/ queue.
