First verify that these setting have not already been customized, as running the commands will overwrite any changes they have made. The following command will show you whether those files exist:
ls /var/qmail/control | egrep 'timeoutremote|timeoutsmtpd|concurrencyremote'
Run following command to update limits
echo "120" > /var/qmail/control/timeoutremote echo "120" > /var/qmail/control/timeoutsmtpd echo "40" > /var/qmail/control/concurrencyremote
The default timeouts are set to 20 minutes, or 1200 seconds. So if the mail server on the other end is not responding, the outgoing email stays in qmail’s remote queue for 20 minutes before it fails. By default there are 20 outgoing slots for email so this can backup quickly. These settings also increase the number of emails which can be sent at one time to 40.
When you have made the changes, restart qmail with the following command:
/etc/init.d/qmail restart
Mail should begin faster now.
