Ok, I did this, and verified that more outgoing processes were started (in the
qrunnenr log, and with ps). Testing 5000 messages to a list with 25 recipients
took:
8 & 1/2 minutes with 1 outgoing slice
5 & 1/2 minutes with 2 slices
exactly 5 minutes with 4 slices.
I noticed that the incoming qrunner was using 10% CPU (according to the pcpu
column of ps) even after qfiles/in was empty, and after all 5000 messages were
processed. I wonder what the incoming runner is doing - any ideas there?

OK, this just means that a message which is tempfailing will have to get
retried for 5 days, before normal bounce processing rules can (potentially) act
on it. I suspect a lot of these addresses are our own accounts which are
tempfailing because they are disabled, in some sort of transition, or have
broken LDAP records - I will look at smtp-failure some more.
Thanks,
Ivan.
