How to increase simultaneous/concurrent email deliveries in Plesk Qmail?

Qmail allows a maximum of 10 local and 20 remote email deliveries/processes simultaneously by default. The concurrencylocal and concurrencyremote files are the ones which handles the concurrent local and remote email deliveries respectively.

To increase the number of email deliveres/processes, you have to increase the values in the concurrencylocal and concurrencyremote files and restart the Qmail service.

The concurrencylocal and concurrencyremote files resides in the /var/qmail/control directory. If the files are not present, you have to create them

# vi /var/qmail/control/concurrencylocal
# vi /var/qmail/control/concurrencyremote

set the required value and restart the qmail service

# service qmail restart

Once done, you can manage the Qmail mail queue using Qmhandle.
