Ok, btw I can see that the value in conf-split is actually the number of
directories in /var/qmail/queue/local(remote,mess,info).
How do you know if lots of emails are getting queued, that I need to
increase the value in conf-split or install another instance of qmail?
By default, the value of conf-split is 23, and I don't know how much
queued emails can this handle.
